Pierre explained that a sane library maintainer could/would use a new
version associated to the symbol even the ABI hasn't changed so that any
application linked against the newer version get to effectively depend
on the new version.

I really think that the benefits outweigh those problems by an order of
magnitude. And as Mike said, it's not worse than forgetting to bump the
shlibs currently. 

On the contrary, with my mecanism if a new symbol appear it's
automatically associated to the new release. Thus it's no more possible
to "miss new symbols and forget to bump the shlibs". I really think that
on the whole, it will be way better than the current situation.

I have a first version of the code implementing most of this and I'm going
to send that info in a separate mail RSN.
