My understanding is that most modules, such as drivers, won't cause any
ongoing performance penalty if they aren't in use. There are some
kernel options that do. and they're sometimes (though not, alas,
consistently, like much of the kernel documentation) noted as such in
the kernel docs.

No. A NPD is a very serious type of coding error with potentially
catastrophic security consequences:
If the code in which the bug occurs isn't being build, though, you're
quite safe ;)
