We only ever used the ID table matching before, but we should probably
also support an open-coded match function.

The subject line does not make sense, what is "also"?  Who is doing
this?

Coming back to this after a week I have no idea what is going on, so
that's a sign that it needs to be reworded :(

thanks,

It's actually been 2 weeks. Were there any other changes you wanted
made in this patchset, or is that going to be it?
