And for those that remain unfixed, how about segregating them in a
separate directory, using an extra attribute on the <dir> directive:

    <dir assume_well_formed="yes|no">

where the “assume_well_formed” directive defaults to “no” if omitted.
That way the known-good fonts can be put in their own directories with
assume_well_formed="yes", and we get the speedup from bypassing the
extra checks on them, at least.
