Unless you have other reasons to create a group, you can just use:
\noindentation\dontleavehmode
\startxtable
...
\stopxtable

Indeed. Thanks for the information!
For the record, this is how the problem is finally solved:
\setuphead[section][after={\blank[sampage]}]
\begingroup\setupindenting[no]\dontleavehmode\startxtable …
\stopxtable\endgroup

What happens when you \hskip is that you switch to horizontal
mode and the preferred to do this is to use \dontleavehmode.
\dontleavehmode

it is sometimes difficult to predict how much remaining space should

You can either reformat your table or put the table in a float
environment to move it to a place where it fits.

Hi Wolfgang,
Thanks for the suggestion, but as illustrated by the second example, copied
here, where the section title is at the top of the page:
\starttext
\showframe
\dorecurse{50}{a }
\startsection[title=spec][before={\blank[preference,big]},
after={\blank[samepage,big]}]
\startxtable
\startxrow
\startxcell[ny=30]a\stopxcell\startxcell 1\stopxcell
\stopxrow
\dorecurse{29}{\startxrow\startxcell 2\stopxcell\stopxrow}
\stopxtable
\stoptext
it is sometimes difficult to predict how much remaining space should
trigger a line break.

Hi Pablo,
Thanks for the suggestion, but unlike the MWE, in the original document,
the table has ten rows and is visually not suitable for a split. The large
row span is meant to represent this restriction.

Hi Sylvain,
\setuphead[title]
[before={\blank[preference, big],
after={\blank[samepage, big]]
In this case, the blank space before sets a preference for inserting a
page break. The blank space after requires to be in the same page with
next paragraph.
Another method is to move the section title to the next page when the
remaining spaces
is below a specified number of lines. The following setup forces a page
break when
less than 4 lines remain on the current page.
\setuphead
[section]
[before={\testpage[4]\blank[2*big]}]

Hi Sylvain,
no fix is required when you allow the table to be split:

Hello Pablo,
Thank you very much for the help. The penalty of \blank indeed brings the
solution closer and it does format the previous example correctly.
However, when I went back to the original document, neither
[before={\blank[preference, big]}] nor [after={\blank[samepage, big]}] nor
both worked. I trimmed it into the following example which behaves the same:
\starttext
\showframe
\dorecurse{50}{a }
\startsection[title=spec][before={\blank[preference,big]},
after={\blank[samepage,big]}]
\startxtable
\startxrow
\startxcell[ny=30]a\stopxcell\startxcell 1\stopxcell
\stopxrow
\dorecurse{29}{\startxrow\startxcell 2\stopxcell\stopxrow}
\stopxtable
\stoptext
Do you have an idea on how this could also be formatted correctly or how
one could inspect and debug the penalty?
Thanks again!
Sylvain

Hi Sylvain,
\setuphead[title]
[before={\blank[preference, big],
after={\blank[samepage, big]]
In this case, the blank space before sets a preference for inserting a
page break. The blank space after requires to be in the same page with
next paragraph.
Of course, you don’t need both simultaneously.
Just in case it helps,
Pablo
