Note that if and when SBCL uses ASDF 3, it will be trivial to update
its contrib to use the one-fasl-for-the-entire-contrib approach,

In the current world, ASDF must still be hot-upgradable.

It is conceivable that we could move toward a world where it need not.
Beware, though, of the perverse incentives that used to exist
in the previous situation where it was not:

You will need some force capable of countering them.
