Please don't call other people's opinions nonsense. https://docs.fedoraproject.org/en-US/project/code-of-conduct/index.html Anyway, I would say that openssl 1.1 upstream was never designed around distro packaging in mind. They probably assumed that it's fine to have just one version of their headers installed at one time ... which is not the case if you need to work on a piece of software that uses the new API, and another piece of software that uses the old API. Conflicting packages mean repeatedly installing and uninstalling things in that case. Not what I'd call good packaging. compat-openssl10-devel are just a distro hack to make it possible to _build_ stuff in koji against the older API, but it makes it a pain for any developer to use the headers (because of the conflict). >> Look at some well designed libraries, gtk2 and gtk3 for example that can >> exist in parallel and have -devel packages that don't conflict. > > gtk2/3 is a bad example.

Symbol conflicts is a completely different issue and conflicting -devel packages changes nothing there. If the devel packages conflict, it just makes it so much harder to use Fedora to actually develop software. It's fine for package building purposes, of course, but actually developing stuff is what I enjoy doing on Fedora.
