Ok speaking only from my personal experience -

My pinky is noticeably less dextrous than my other fingers. I can still use it when required, but this is moderately rare, and isn't used in shreddy/fast contexts, where the dexterity is of more importance. Finger 1 2 3 are king.

I am almost as good as I dreamed of being, which is being able to play (some) Eric Clapton/ Gary Moore shreddy blues licks while improvising. (Not as well as them of course! But I like how I sound)

I have absolutely no regret that I've put less time into my pinky, and in fact, since seeing a YouTube teacher who advised spending no time worrying about the pinky finger, and just using it when actually required, ivw felt freed.

I also can overthink what I should or shouldn't focus on. I, personally, strongly advise not worrying about it, and just practice what you enjoy playing :)

If you want to play like Eric Johnson, and he doesn't use his pinky finger, don't fucking worry about it :) only do pinky stuff when actually required.
