IMO the issue is not copying cherry picked good features from Reddit, but to indiscriminately copy features because “since Reddit has it, Lemmy got to have it too”, without paying attention if they actually benefit the Threadiverse.
Bots are one thing like that. Communities could have features built in that was not possible on Reddit since admins are part of the community now.
Good catch on bots - they’re a great example of that, since the underlying idea (less busy work) is 100% worth copying but not the implementation.
In fact IMO Lemmy bots are already a bit too similar to Reddit bots in a bunch of undesirable ways. For example they’re created and kept as “pseudo-users”, instead of tools associated with a (human) user in their profile.
