> Sometimes a new feature needs maybe 2k lines of code split over 10-20 or so files

I still disagree. Why was the feature not split up into more low-level details? I don't trust that kind of project management to really know what it's doing either.

I am not promoting micromanagement, but any large code review means the dev is having to make a lot of independent decisions. These may be the right decisions, but there's still a lack of communication happening.

Hands off management can be good for creativity and team trust, but ultimately still bad for the outcome. I'm speaking from my own experience here. I would never go back to working somewhere not very collaborative.
