Thinking of a clean instal of v.17

I’ve used Kodi for a few good years now.
I have fine tuned everything to my taste but I’ve also made some questionable installs now and then (addons, repos), that I tried to undo one way or an other. It has been a journey in which my relationship with Kodi matured, as I have tested and found what works for me and what I need.

Everything works nicely at the moment, with the occasional crash.

But my question is, should I do a clean install of v.17? Start fresh and get rid of leftovers from past bad installs of addons and repos?
