Well, some definitional work would be needed. That specific problem
seems sensibl solveable by defineing those to be relative to the control
file.

I don't really care much about Oliver's usecase TBH, but I would very much
welcome making it easier for application developers to package part of
ther in-database application code as extensions without either requiring
a selfcompiled postgres with a custom extension dir or them having have
root access to the machine running postgres.
Providing them with access to a directory that's only configured as
additional extension directory for a development cluster would be a huge
improvement.
