I have read the whole discussion and I would like to share my opinion,
even if I think it could be a bit off-topic.
Given that Fedora community alone, cannot educate every upstream
developer about unbundling, and considering that it is a problem that
interests all main Linux distributions: I think that Fedora community
could (and should) propose to other Linux distribution communities to
make a general effort to kindly ask upstream devs to reconsider their
work, enforcing unbundling.
This will take years, but I think it is a way we should cover.
How Fedora wants to educate 'upstream' when it rather fails on many levels when we talk about library handling.
Fault #1
Fedora badly supports multiple libraries of different version - i.e. typically full rebuild of whole repo is made when new library is introduced - which is typically quite bad idea (and this is not just because of simple version change requires reload of many GB of packages)
(I've already complained that usage of rawhide & rpmfusion is getting silly)
Fault #2
Version of libraries is wrongly handled on packaging level as well as on build level and many library packages are not correctly versioned - so if someone believe there is some use of libname.so.major.minor.patch - for RPM it's mostly useless and if symbols are not properly version inside library, dependency will simply not work - and just adding 'constant' version string to every symbol inside library will not make this work

I get the feeling this is related to Fedora not aggressively using versioned package names for libraries, or at least enabling some kind parallel installing capability. SUSE used to follow a policy similar to our current one, but switched due to the insanity and impracticality. Mageia also uses a policy almost identical to SUSE's.
For an example, here's SUSE's policy: https://en.opensuse.org/openSUSE:Shared_library_packaging_policy
I've been meaning to ask about why we don't do this for a while now, but it seems like now is a good of a time as any...
