I seem to remember that's the reason indeed (though I can't find any reference
right now). For this case, kpse_find_file is called with false as its last
argument (must_exist), so that it doesn't try to "make" the file with an mk* script.

I tend to agree. Morover, if some day we want to use mktextex for on-the-fly
installation of packages à la MikTeX, we'd better have mktextex triggered by
\openin, since it's used by \usepackage before doing an \input, iirc. Then, it's
up to mktextex to do the right thing if the file is not actually meant to exist.
