I literally never had this problem. Sure, I broke my system in order to install something new (Eg. I switched to Wayland + sway recently) but that's constrained to when I'm consciously installing something.

I can understand the use case of having to run 200 micro services or something too powerful for my machine.

I don't understand my local environment automagically becoming "brittle".

I assume things may break after pdate on trash operative systems without an official package manager like Windows or Mac, but other than that...
