The upcoming 4.4 release has a generator based on a template, which was this one. We will look into whether we need to put that feature on hold from the 4.4 release while we work through this, however, yes the idea is that there would be a template set of terms that any instance could customise and adopt.
Personally I use third party apps like Sill, Fediview and Murmel and Phanpy which all have versions of algorithmic timelines for catchup. Whether something of this kind of built in to Mastodon in future is still open for discussion, but I’m not aware of a plan to spend time on it in the next couple of releases at least.
