Fedora opens up to bundling

... it's often too late, because you've already shipped, and your users are having a bad time.

As someone who has observed a lot of bug reports due to library version skew with unbundled Firefox --- we have not been getting along "very well".

You've also seen countless security problems fixed by bundled-library applications updating the whole package. (It's worth keeping in mind that any application vendor who deploys on Windows or Mac or iOS or Android must bundle libraries, must monitor them for security issues, and must provide timely security updates for the entire package on those platforms, so for them, unbundling on desktop Linux reduces the work required by a negligible amount.)

> But I've seen less than a handful of apps have serious problems when a library is upgraded, and such problems have always been treated as a bug in the library

That's odd. In my experience, users blame the application when it doesn't work. E.g. when Firefox freezes on a Web page using HTML5 canvas, the user blames Firefox. They do not say "hey, this must be a bug in the system cairo library!" and complain to the cairo developers.
