For me, a browser is a tool, not a way of life.
Every time I (re-)install K-M, I have to make sure I save and replace all the little homey comforts I have fixed it up with. Always forget where/what half of it all is, too, heehee.
To learn the new critter's peculiar habits all over again, find new fixes and workarounds for the quirks I don't like, and learn to live with the ones I can't fix (lol, as if I could leave bad enough alone) too often would be a pain. Takes me some months to get around to every detail, so T.G. there isn't a new version out every few weeks.

Keep up the moderate pace.
