Seems so. If the upstream authors think that breaking APIs are fine then I don't think it's Fedora's place to do anything about it except maybe advise people what libraries not to use.
Irregardless, I love Fedora now. It's grown massively since the old 'Fedora Core' days and it is the most usable and interesting desktop platform for my purposes.
I was reminded of this last night when I booted up my old Debian testing/Unstable laptop and decided to do a apt-get dist-upgrade because it hasn't been updated in a year and a half. After about 2 hours of trying to massage apt-get and aptitude into getting back to a usable system I realized that the only thing I could do to get a usable system without a re-install is the aggressive use of apt-pinning to degrade my system to stable and then upgrade it to testing/unstable. I love Debian a lot also, but I am totally over the whole 'rolling release' thing and stable is just too old for Desktop Linux stuff. It's a great concept (rolling release), but I don't think it has much of a future.
All in all it's fantastic work that Fedora does. I have almost switched over entirely to using it for all my desktop/laptop needs.
