yes but active usage doesnt mean it was not used?
If their criteria was “at least 1 person uses it at all, sometimes” then it would not have been removed 🤔
likely no maintenance effort at all.
The maintenance comes less from the code and more from making sure that every single menu added or changed in any way continues to behave correctly in three different sizes with themes and everything.
Hosting data yourself wouldn’t be required, but it would become an option.
You’d have the option of leaving your identity on your home server, or a separate domain/website, or host your data and identity but use another instance to federate.
Though, designing UX for this will be an interesting challenge.
