Unfortunately Fedora has been making a lot of similar decisions to Ubuntu lately, although it's still better IMO. I'd say coming from Ubuntu, Mint is probably a lower learning curve anyway.
I could also see people not wanting Wayland by default, though that has been working fine for me and the software I use.
I've only been using Fedora for 2 years, but apart from those two decisions, it's been a lot more stable than my time with Ubuntu.
It takes a single line change in /etc/gdm/custom.conf to disable it.
It does not actually say how it interacts with existing rpms or whether said rpms will continue to exist or be maintained in the future.
I would say it's too early to get up in arms about just yet.
Me personally, I agree with this approach, but a lot of other people clearly won't.
