* Is \directlua always available?
  Or are there formats with undefined \directlua that is
  available as \luadirect?
* Anyway, you need to check for LuaTeX and it's version.
  I doubt, that you want to support *all* older LuaTeX versions.
  Also the syntax of \directlua has changed.

Package ifluatex.sty can be loaded by iniTeX and provides
\ifluatex, \luatexversion, and \luatexversion. It only
requires \directlua. Should I change this that in case
\directlua is not available that \luadirect is tried?

Yours sincerely
