That's something I'm much more into these days, too. But I'm even more into getting *me* to perform a certain way.
Oh yeah (yawn*), this is partially about "tone is in the fingers" - but it's not exactly that, it's more about finding a good/great sound and commit yourself to it and then trying to push it as far as you can, utilize it for all kinda things and so on.
When listening to, say, players like, say, Paul Gilbert or - possibly even more so - Greg Koch, one will notice that they're getting pretty much anything they need out of very, very simple sounds. Sure, in case they can, they do enhance things a bit, they also usually use top stuff - but when you have Greg Koch and throw a Fender-ish amp with any kind of non-heavy drive in front (and perhaps some delay) at him, he'll be every bit Greg Koch as much as it gets. And nobody would ever notice any sound-related flaws.
These guys switch things on, see what it sounds/feels like and then do their thing - which completely translates to them playing their curated setups. There's hardly much pedal step dancing or wild things in their configurations, and you also rarely hear them complain about whatever sounds they may need.
I don't think I'll ever even remotely touch that level of self-consciousness, but it's the direction I want to focus on much more than on just another modeler, pedal, guitar or whatsoever. I can get each and every sound I may ever need for the rest of my life already, so hunting down more stuff is pretty pointless. Sure, there's also "want" vs. "need" - and as said, there's some things I could do with, but there's really no pressure.
