Ah, OK. I didn't realize this before, thanks for the clarification.

I somehow expected / hoped that it was possible to explicitly point ld
to a specific .so version, but apparently this isn't the case.

I'm interested in this because in openSuse, there's currently no
separate devel package for sensors. I plan to make one before moving to
3.0.0, so I need to learn how this is supposed to work.

I also don't plan to make both devel packages installable in parallel,
it's not worth the effort.
