Can someone explain me *real quick* what is the multilib good for? - or more precisely, why whould anone run 32-bit software on x86_64 OS?

From what I googled, it look like everyone does it yet nobody explains why :D

Thanks for the insight. Yes, I can see the advantages. However, have things really gotten so bad that it justifies ejecting part of the community?

The cost of i686 support is not insignificant.  Most of that happens upstream (like features only getting accepted when there's an i386/i686 implementation).  There's little we can do about that, but:

In fedora, we are also a point of contact for weird bugs which someone needs to triage.  I really don't want to do that, but due to the lack of secondary architectures, I'm often forced to because i686 breakage brings development on architectures which I actually care about to a halt.

I can justify this work if it helps downstream (so that we can be confident that customers will be able to run their legacy software going forward).  But with the current divergence in build flags, it is fairly questionable whether my work can deliver such a benefit, and that is frustrating.
