My motivation is different. If you have any macro in a table (or anything 
that requires multiple runs to get the size right) that uses a counter 
(e.g., enumeration), then the numbers will be off. That would not happen 
if a counter is frozen when trialtypesetting is on.



P.S. Would not the use of \startcombination\stopcombination be an
alternative to the placefigures within a table?


combinations only give regular grid. Sometimes you want an irregular grid. 
For example, the OP wanted


+--+--+
|  |  |
|  | Fig2 |
| Fig1 +--+
|  | Fig3 |
|  |  |
+--+--+

Such layouts are not possible using combinations.

I was going to suggest such things...

Here is a case where a float is not being used as a floating object in
that we want to control placement through location=here or, better,
location=force. We do this as users for we want to produce a caption
as well as make an entry into the list.

However, floats have some limitations: for example they cannot usually
handle multiple pages (except for some table splits), nor can they take
\startcolumns \stopcolumns, and I am sure that there are others.

Does anyone have suggestions/ideas around these kinds of issues? Should
a float with location=force be treated any differently?

Another annoying issue with floats: \startplacefloat\stopplacefloat
initiates a paragraph break. If one refers to a float (figure or table)
somewhere in a long paragraph, one might like the float to be anchored
starting from that location. I achieve this using
\startpostponing [+0]
  \startplacefigure
  \stopplacefigure
\stoppostponing
but this does not always work well. In addition, this is not very
satisfying (as it makes for ugly source code). Also, one might want to
use location=right or location=left without using "hang" and counting
lines. Hans has repeated that floats are complicated beasts and such
features would interfere with paragraph building. OK (But dare I say
that LaTeX does not seem to have any problem with this.)

Varying the contents of the table reveals that It is skipping two times the

Is this an invalid combination of features I’m using or am I doing something 
wrong?


The contents of a table are typeset multiple times to get an idea of the
height and width. Here is one option:

\useMPlibrary[dum]

\starttext

\bTABLE[frame=off,align=low]
\bTR
\bTD[ny=2]
 \placefigure[here,\iftrialtypesetting nonumber \fi]
 []{left twoup}{\externalfigure[mill][width=2in,height=4in]}
\eTD
\bTD
 \placefigure[here,\iftrialtypesetting nonumber \fi]
 []{the first}{\externalfigure[spider][width=2in,height=2in]}
\eTD
\eTR
\bTR
\bTD
 \placefigure[here,\iftrialtypesetting nonumber \fi]

Wow, I am quite satisfied with this solution.

Btw, I couldn't find any details for that \leftboundary command either 
in TeX [1] or ConTeXt [2] command references.
The \leftboundary command uses a new LuaTeX primitive which means you 
can’t find it in a TeX [1] reference.

when generating example in the following article, I can't get rid of
overfull in Old greek paragraph even if the tolerance is set to
'verytolerant'.

In time of producing the result image it was sufficient to set the tolerance
to 'strict'.

(1) How can this be fixed efficiently?
(2) What has changed internally?

Thanks for any hints,

Wow, I am quite satisfied with this solution.

Btw, I couldn't find any details for that \leftboundary command either in TeX 
[1] or ConTeXt [2] command references.

I've tried it just with \hbox{} and it works as well.

Couldn't this be generalized in a way - if you want protrusion even in edge 
cases, any inline commands have to be wrapped in \hbox{} ?

Good to know, thanks. I take it rather as a limitation.

Use case:
- book uses global indentation
- there is poem typeset in narrower block
- there is punctuation in the first verse which disrupt optical margin alignment

Are there alternative ways?

Btw, from end user perspective I'd expect it should work by default without 
further tweaking.

I’m afraid that doublesided alternative disables duplex printing.


sure, that's why we have 'portrait' and 'landscape' as directives
