I really think it is. Even at the scale of a single app it may sometimes make sense to have multiple versions of a same library, if for instance it implements a given algorithm in two different ways and both ways have useful properties

Then shouldn't these APIs be exposed as different libraries?

maybe ? in the end it's up to the person developing said library

I have seen this (linking with multiple versions of the same library) for maintaining backwards compatibility, for example to support parsing a data file from a previous version, but never for selecting different algorithms.
