Is waiting 3 seconds before updating the user performant? I'm doing this as a little test/proof of concept before adding all sorts of stripe functions for it. But essentially I'm doing this to add all sorts of extra details in OAuth accounts, as you can do this very easily with credentials but not so easily with OAuth.

I've got the timeout so that it updates the user after the user is created in the database, as if there was no timeout, it would only update on the second login of the account
