I once tried to disable all but the ones I actually need. There are close to 200 CAs trusted by my devices and I only need to trust about 15 of them. But it’s a colossal pain in the ass to figure out which CA an app needs, so I abandoned that experiment.
Yeah, I too had that ambition once, but I didn’t even know where to begin, since I don’t know how to find out which once my apps, websites and other services actually need. Other than investigating whole chains of collaboration between the various owners and devs of those services. Arduous much? 😅
I used a proxy to look up which servers the app was trying to talk to, looked up the cert from the server and which CA I needed. It was very arduous, especially when you installed a new app and just wanted to use it, e.g. for parking. This made me stop doing this. When giving talks to junior devs I used to explain that security and convenience are almost always on opposite sites and you need to figure out where between the two extremes you want to sit. In this case I opted for convenience.

Sounds like a job for a machine.
Oh stop. You’ll never get this corner of the internet to admit such things.
Careful! They’re gonna whoop our asses:
