Strongly agree with this. It's about leaning into Conway's law. How micro the services get is a variable, for sure, but it's definitely worth considering as partly technical and principally an organizational problem.

With good defaults, you can have a dev tools / platform team create a blessed path that most teams will easily adopt so you get a mostly standardized internal architecture (useful for mobility). It's harder to allow for lessons learned from one service team to transition to the org as a whole, but if the dev tools / platform team has great Principal SWEs, it'll work. It does mean that you need great people on the platform team, though, since mediocre people will attempt to freeze development to fixed toolchains and will be unable to see the big picture.

I think Amazon does a good job with their Principals here.
