I wonder what the rationale is behind this ... when we redo the matrix
code we can prune such empty rows in lua. I always thought that \crcr
was more clever.

Hi Hans/ Aditya,
With the latest beta, \startmatrix's final \NR creates a
superfluous line, resulting in ugly output:
Bugfix:
In \dodefinemathmatrix, change
\setuvalue{\e!stop #1}{\dostopmathmatrix}%
to
\setvalue{\e!stop #1}{\dostopmathmatrix}%
If someone wants to correct this in a working document, add
\let\stopmatrix\dostopmathmatrix
somewhere before \starttext

\startformula
\startmatrix[left={\left(\,},right={\,\right)}]
\NC 0 \NR
\NC 0 \NR
\NC 0 \NR % removing this fixes the output

I don't know why \setuvalue gives an extra space. Hopefully, you or Hans
will be able to figure that out.
no clue yet but
\unexpanded\def\dostopmathmatrix
gives an extra row
Simpler example:
\def\A{\halign \bgroup ## \crcr}
\unexpanded\def\B{\crcr\egroup}
\def\C{\crcr\egroup}
\starttext
\ruledvbox{\A A \cr B \cr \B}
\ruledvbox{\A A \cr B \cr \C}
\stoptext
Same results with MkII and MkIV, so this is not a luatex issue.

some day Taco and I will arrive at dealing with this lookahead in the
perspective of protected (\unexpanded in context) macros issue in luatex
(makes a nice topic for discussion on one of our travels to a conference)
