Having different sorts of characters with official rules variants/updates/modules has been part of D&D since AD&D's Unearthed Arcana, or, even earlier, since "Official" Dragon Magazine rules.
Unless you are DMing at a tournament or are in a Living Campaign, you get to pick what you want in the game. That can be a consensus in the gaming group, DM choice at the beginning of a campaign, a vote, or something else.
If you are worried about being forced to use rules you don't like at a convention, RPGA event, etc., then don't DM at those events.
