Maybe a controversial opinion, but CUPS has always been an enormous nightmare for me anyways. The one thing I hate about any project is the "fiddly" bits, and CUPS is 100% fiddling. The UK had to make it a member of parliament to keep it from being locked away for all the fiddling its involved in. Maybe now it can be turned into something that doesn't require a degree to get it to work (in practice, not in theory, there's a large difference there), or it can be abandoned entirely and something functional can be made?
On the other hand, it might not matter in the next five years or so once Windows officially reveals that (to the surprise of nobody) they're just going to become another distro of Linux, so there's that.
