Yes but the same 'add suffix when not set' code is used as in pdftex, 
but luatex did that only in then non-braced case (whjich pdftex doesn't 
have) while actually checking with a .tex suffix when not found is a 
kpse feature controlled by some flags in the cnf so even for pdftex one 
can wonder what is the right way (support for {} shouldn't be too hard 
for pdftex). Keep in mind that adding a .tex in case of no suffix being 
there makes it impossible to open files without suffix.
