I really like your comment about "re-architecture". I 100% agree with you.

To expand on this, I've found that often, the best way to make a change is in two steps: First, make the change easy (the re-architecture). Second, make the change that is now easy.

My best software development experiences have been in cultures where this way of working was common.

It is a shame that these cultures are not more widely spread; and I mostly blame GitHub: the lack of good support for stacked PRs or patch series or whatever you want to call it makes it harder than it should be to work in this way.
