Yes. Then again, that fails in myriad small ways, nor does it test
any of the new code, so I have not paid any attention to it so far.
The trip test failures are something to evaluate in the step from
luatex 0.9 to 1.0.
In general though, to anybody who wants all of the idiosyncrasies
of TeX82 to be retained a 100%:
luatex is not for you.
Some of TeX82's behaviors are just too obscure to be transfered to
a program whose internals are supposed to be extensible and accessible
(and the "l" keyword is one of those).
