This isn't possible with the current A-O-T, since A-O-T tries
to resolve the mappings statically.
I could modify A-O-T to make it possible to do what you say.

It strikes me as a bad idea, but if there's popular demand,
I don't see why not let people have what they want,
as long as it's not the default.

CLC and CL-Launch use centralization, and no one seems to complain
(maybe because no one use CL-Launch; but CLC seems to be somewhat used).
Centralization is just *required* when source comes in shared locations
where users don't have write access. So it's a better universal default.

I'd rather have no translation by default than this decentralized mess.
At least, it would make it clear that you need to configure things.
But Centralized FASLs strike me as something that will work everywhere.

I'll make that happen next week.
