But Earth-65 has literally just one, which is Gwen. If they count every dimension then I could argue there's too many of every character.
I mean pre-humility Thor was still worthy of the Hammer - it's only when his pride outshone everything else that he got dumped. iirc being humble wasn't a requirement, especially for a warrior culture like Asgard. Thor-Gwen seems to be active judging by how people worship her as a Warrior God.
