So a few popular Linux distros decided to drop a few major packages like how red hat dropped rpm packages for libreoffice in favor for the flatpak packages.

If more distros decided to drop more packages from their main repository in favor for flatpak packages, then are there any obvious concerns? From my personal experience, flatpaks didn't work well for me. If flatpaks become mainstream and takeover the linux distros, then I might just move to Freebsd. I just want to know if there is any positives to moving away from official repositories to universal repositories.
