If I wanted a broken bloated user expereince I would have kept on using Microsoft Windows 30 some odd years ago. I don't understand the need of some to turn Linux into the aweful user experience of Apple/Microsoft. I am.100% on board with making things easier to use, but snaps and flatpak and containerization of everything is not the answer. Whenever I accidentally click the wrong button a 20 second install ends up taking half an hour and the end result is often a crashing buggy mess.
The concept has actually been around 20 something years now and what looked kinda cool has never turned into practical solutions to solve the excess number of packaging solutions nor has it been utilized in a sane way as a complementary solution. I can understand it for releasing newer versions for many distros and older distro versions if you can make it work adequatly.
