Which reminds me of something I was wondering yesterday:

Couldn't we just, right now, say "'SOURCE_PREFIX_MAP v0' uses the
encoding of $PATH", so consumers/producers have something concrete to
play with?  We could subsequently release a v1 that adds supports for
colons, but as they say, "release early and often".

I'll go ahead and add this to the agenda.

Cheers,
