I'd say it's normal, but also normal to not distoe hop - everyone has their own preferences and Linux gives people the freedom to do what they want.
I have wiped my distro before just because I felt I'd let it bloat. I like tinkering and installing all sorts of random packages a long the way but am not good at cleaning up. I stayed with the same Distro - OpenSuSE.
But before OpenSuSE I used to use Mint. I liked Mint but I managed to break the updates in a minor but annoying way with a customisation I did on one version prior to an a major system update. When I decided to fix the problem I decided to distro hop.
I also have a HTPC and I just reinstalled my distro this week - I did this to wipe Win11 off the device which had been pre installed and I kept when I installed Linux "just in case". I haven't used it once and it was taking up half the hard drive. So I figured I'd back up my home folder, wipe the computer and reinstall Nobara and then restore my home folder. Worked like a charm, and I was back up and running in about 30mins.
It also gave me a new appreciation for User level Flatpaks, much of my software was already there, installed and ready to use. I did even consider distro hopping again but Nobara has worked well in my HTPC.
So yes, Distro hopping is normal, reinstalling on a whim is normal, and staying with a distro and just letting it update for years is also normal.
