Tested with 2014.02.14 beta, and it is a big improvement. Again, sorry
it took so long to test.
If I use hoffset=3pt, it seems that some underbraces get 3-pt borders
but others don't. For example,
\setupmathstackers[vfenced][hoffset=3pt]
\starttext
\placeformula\startformula
\underbrace{15\,\tf cm}_{L}
\times
\underbrace{15}_{L}
\stopformula
\stoptext
The second underbrace has the 3-pt borders, but the first one looks more
like a 0-pt border (though hoffset=0pt makes it have a negative border).
Is it due to quantization, in that the extensibles grow in fixed-size
units?

Using 2013.05.28 00:36 MKIV (from vanilla TL2013), the left brace tip
starts under the vertical bar of the 1, instead of enclosing the serif
as well. The right brace tip ends between the last two tines of the
m, instead of enclosing the whole m and its serifs.
With 2013.04.09 10:38 MKII, the brace tips extend just slightly beyond
the 15 cm, which is better. However, they seem slightly too close.
As a test, I ran the comparable plain-TeX file through LuaTeX and PDFTeX.

The gap between the right brace tip and the text is slightly greater
(with either LuaTeX or PDFTeX), and it looks right.
(With the 2012.05.30 MKIV on live.contextgarden.net, the result is
similar to the Lua/PDFTeX versions, though not identical, and also looks
reasonable.)
it has to do with the fact that we have opentype math fonts now and
these are not compatible
what you observe is the fact that we have a discrete number of sizes
till we run out of them and go stretchable

\setupmathstackers[vfenced][hoffset=10pt]
is it looks like these commands have built-in \limits, these are now set
for
