this kind of interrelation needs to be removed

i dunno how it is in other codebases but there is such a mess of things interconnected but not actually related, that can be separated, and it makes the entire structure brittle

it took me a week of bashing my head against it to finally go "oh yeah, this is why you put one type per package" and then you can actually start at the tips of the branches and replace them with different or better or entirely separate versions without upsetting the whole tree
