I maintained my own emacs config for a while and ended up moving to Doom mainly for a more thoughtful shortcut config. I spend a couple hours every once in a while tinkering for fun (and to fix issues with my workflow).

Sure, you may be tinkering more in emacs and working less, but free play is an integral part of growing skills, as is feeling a sense of joy when using your tools. It’s okay to do things without a goal in mind.
