I've been tempted to go fix it, but it's a little subjective, and I have no idea what kind of argument I'd need to put forth on a pull request to get them to actually listen to it.

I think what's needed is for them to add MANY different ones and then let communities trial them until finding the ones they like vs the ones that don't work.

I am pretty certain that reddit internally weights subreddits when they like them or dislike them, which improves or harms their time spent on /r/all. This is obviously something that federation can not do because there needs to be a certain amount of fairness.

One thing the "activity" one does put in our favour however is the fact that once federated Hexbear's visibility will be monumental because everyone here is a bigger poster than everyone everywhere else.
