Hi Hans,
The unit scanner in LuaMetaTeX fails for any of the "true" dimensions.
With this test file:
\starttext
\vrule width 1truein height 1pt depth 0pt\relax
\vrule width 1in height 1pt depth 0pt\relax
\stoptext
I get this output:
tex error > tex error on line 2 in file ./lmtx-true.tex: Valid keyword expected, likely 'true'
