I have no drift issues, but this is a good thing for those that do. Cheaply replaceable, and I am sure third parties are going to be tearing down the schematics to get right on it.
this isn't a solution tho. the solution would be to use better stick modules.
from my experience Sony's controllers are the worst when it comes to drift (excluding joycons, which have completely different types of sticks that are simply the worst in every way, they're so shit... like wow...)
in the last 3 years I had to replace 3 Dualshock 4s and my launch DualSense also already has drift.
and it's always the same kind of drift too, it's the left stick drifting upwards on all of them, most likely caused by playing shooters where you click L3 a lot while pushing the stick forward.
meanwhile my launch Series X controller works perfectly like a charm, the right stick is still so firm that I can set all my deadzones to 0, and no drift on the left stick even tho I play just as many shooters and click the left stick just as much while pushing it forward...
more actually because I mostly play Fortnite on Xbox where I have Sprint on L3, while I mainly play Apex on PlayStation 4/5 where I use auto sprint and only have the Ping bound to L3... so my L3 clicking should be way more on Xbox than on PS4/5, because you constantly press sprint in Fortnite, like every 2 seconds or so.
I also read a while ago that Sony is the only one who uses a different stick design, while the Switch Pro and Xbox controllers basically use the same mechanism (or extremely similar modules).
so there's something the modules Sony uses that seems to be extremely vulnerable to clicking L3 while moving the stick. otherwise I can't explain the exact same drift issue that I now had on 4 controllers in less than 4 years, while the same doesn't happen on Xbox (I don't play Switch enough to accurately assess those Sticks)
the only time I ever had to replace an Xbox controller due to stick related issues is when the stick was so worn-out that it didn't properly center anymore, which takes years and years
