Obviously, this will require Debian and such to bump package versions and force users to update all of their CL packages with every SBCL release.
This is what people have to say about it, so far:
<_deepfire> What people think about rahul's idea to distribute programs as fasls? Of course that will mean new package versions of everything, eevery time SBCL is updated in debian.
<Krystof> that's no fun. Distribute heapdumps instead!
<cmm> it's not a bad idea.
<lichtblau> loading McCLIM from fasls is slow enough that you might as well compile the sources and be on the safe side
