>Your ecosystem has gone so complex that you can't test it anymore.

An operating system with billion+ install base, and millions of developers tends to be complex. I'm not sure what you're proposing here, have your platform/software be more niche? Somehow get all of them to fall in line?

>So instead of handling errors properly you suggest to implement a convoluted user flow that offers always failing actions (install a printer when there's none available).

How are you going to "handle errors properly" if the publisher of the software in question went out of business?
