I know I say it in the comments but I'll mention it here again: I don't want to come across as being pedantic with the requests. I just want the codebase to remain consistent and as high-quality as possible for as long as we can, before we inevitably have to start working fast and hacking things to meet customer demand. The better the foundation, the easier we'll have it later on.

Preferably, all of this would be rules in some static analyzer, but I have no clue how to set that up, so it's PR comments for now. I probably should write some analyzer or linter or something, as this will break down once I'm no longer the only reviewer.

I think all this is taken care of but github is still blocking merge, not sure why. Want to stamp?

all resolved

Much better!
