Well, it was not my idea (this is from Compose/Gadfly) but i somehow
understand that for some optional features of a package some optional
imports might be helpful. Especially in the area of BinDeps (or other
binary import) dependencies as they might be -depending on your platform-
hard to build.
But i wonder, if precompilation is locally (not centrally), what is the
problem. The set of packages is available/not-available at the point of
compilation. Maybe it could be marked in Require what is imported and what
imported conditionally.
