Why is Guild.owner typehinted as Optional[member]?

[ImNimboss]

Guild.owner in documentation is typehinted as Optional[member], but is the Optional[] necessary?
I'm not very sure if it's possible to have a guild without an owner, therefore I think the Optional[] is unnecesary. I may be wrong, feel free to correct me.

Intents can cause the owner to be None. (Specifically lack of intents.members)

Oh ok thank you!

Also guild can have no owner, e.g. TnS deletes them.
