Of course built-in support for RSS would be better. But what are the chances of that happening?

Probably better than browser makers committing to maintaining an xslt library.

They didn’t have to maintain it. There was a simpler solution and switch to a library that wasn’t broken.

We already had it, both Firefox and the old Opera supported viewing (and subscribing to) RSS feeds.
