It's that we don't have a critical path "must load these modules before
doing anything else" phase of our boot; and if we did, that phase would
be a horrendous performance drain since everything else would be waiting
for it to complete - as each module is loaded one at a time in series.

Additionally since that doesn't permit blacklisting, or even insertion
of updates, etc. it wouldn't be significantly different than compiling
it into the kernel in the first place.

Except the kernel is already critical path, and is faster at doing this
stuff.
