If I try and run the LuaTeX provided by ConTeXt, I just get an error

value on line: OSFONTDIR =.
This is LuaTeX, Version 1.24.0 (TeX Live 2026/dev)
system commands enabled.

kpathsea: Running mktexfmt luatex.fmt

I can't find the format file `luatex.fmt'!
We started with some generic plain but as luatex plain got hijacked we
decided not to rely on whatever is used to make formats. We always had:
mtxrun --script plain --make
and then
mtxrun --script plain foo
So when an issue with plain is reported that is what I know and
therefore use.
In fact, originally we have a bit of (generic) infrastructure for any
macro package (initialization etc) but dropped that idea because it's a
waste of time.
Anyway, it's only for us / curious context users as the only other plain
luatex users that I knwow have their own setup.
