For sure, general bookmark list is replaceable, same for relay list, mute list, group (NIP 29) list and a few more. Kind 0 and 3 act as replaceable although they are not in the replaceable kind range.

one thing that would be very cool is if your relay would keep + return multiple versions of replaceable events, particularly when the filter has a limit > 1

i.e.

kinds: [0], authors: [], limit: 3

if you could return the last three versions of the kind 0 you know of that will be a very good thing
