You are right. In fact the 'different versions of libraries' thing is
largely an orthogonal issue as a modular or non-modualar rbd driver
would have much the same set of issues here.

Moreover, one Fam's patches (hopefully simplified) could still help
here by permitting (e.g.) a blkrbd-new.so & blkrbd-old.so (hopefully
with more useful names), for those with an allergy to weak binding.
