But this is exactly my question: is it enough for LaTeX? Because I don't
want to have user reporting failure in a couple of weeks because LaTeX
is leveraging another feature that I don't know about and having to go
back modifying things.

So: I will make the new file primitives behaving like \input. But this
does mean that it is not possible for these primitives to deal with a
filename without extension.

Is it OK or not?
