An individual topic shouldn’t be too bad. 
But having some extra tools on hand to tackle all the other outstanding ones too may tip the balance and help speed the task up (probably worth another ‘’ for extra luck 
)
ActivityPub Plugin may be a good test topic for this as well.
Though I think my main advice for any newer sites reading this is, ‘avoid creating kitchen sink topics in the first place’. Improvements to the cure is nice, but I think prevention is still the best option if you can nip it in the bud early enough.
