I think that is WIP to "wear a moderator hat".
Luckily, multiple accounts are widely supported.
Most admins will have multiple accounts, an official-hat account and a casual account.

After some federation drama, i believe marking posts as "official" or not is in the works (as opposed to mod/admin always being official). I dont know if the "official" hat also aliases the user (so there can be a "moderator" account that any mod can assume)
