One big problem with this is that it is tantamount to putting back the
kallsyms_lookup kernel module export, which is considered verboten by
certain lkml bigwigs. Heck, the simple module_get_byname() patch was
refused, which could have made some of the current bloat unnecessary.
Luckily, such anti-cooperation from lkml is rare, but on this subject it
is clear.

Perhaps - though of course it comes with the price of hoping someone
else will do the maintenance; losing control over design / release
schedules. It would not be a panacea.
