This means the pdf backend can't find the font we passed to it, this
used to happen with outdated names database, i.e. we are passing to it a
font that doesn't exist or can't be found by kpse. May be you generated
your database with OSFONTDIR set and then run luatex with it unset?
This shouldn't be an issue actually, as luaotfload will update the
database in such case.

Well, the code is getting too hacky, I guess I need to set down rewrite
it with all these issues in mind not as an afterthought.

Instead of adding yet another hack, people should just use the already
documented syntax for loading fonts by filename:
One already knows he is using a luaotfload specific feature when he
trays load font files with extensions.
