Most people don’t do it on their main system. They either have a secondary/hobby system they are playing with, or do it in a VM.

Or they are dual/triple booting.

It’s why live discs/drives exist. You don’t have to have it installed to try it, and you can even install on portable drives. So you don’t have to fuck with your main device to distro hop you just load up whatever you’re using next, try it out for a few days or weeks, and move on.
