I'm thinking, for example, of a library that uses cond-expand to include files containing implementation-dependent code and, for clarity, wants to put all of the implementation-dependent imports in the same files as the implementation-dependent code.

This can be achieved trivially by cond-expanding imports of
implementation-specific utility libraries.
