It all seems like bikeshedding.

Optimistically I could think it’s because all the hard stuff is solved so we argue over things that don’t matter.

Cynically I could think that arguing over this stuff makes it so we never have to test for competence. So dumb people can argue over opinions instead of building things. If they argue then they never get tested and fired. If they build, their thing gets tested and fails and they are fired.
