Does your capacitive phone screen wear smooth over time?
(The point being hopefully they’ll be made of something that doesn’t wear down from human fingies)
The case around it does. That’s what I want to replace.
I assume the same way the steam deck gets replacement sticks. You’d replace the entire thumb cap and run a wire under and to a specific connector. So its unlikely you’ll get a third party solution with capacitive touch but getting official parts shouldn’t be impossible either, just more tedious.
