I don't see the "ouch" in that. There's very little to gain from having
such a setup.

The only *real* benefit is the possibility to have multiple .so.whatever
versions of your library around, so that you don't need to recompile programs
depending on a library if that library changes it's major version, while having
one current "-dev" header package. 

(Actually, I think only debian and debian-esque distributions have this 
peculiar setup)
