yeah.. that us the obvious pattern.. but i was thinking about more fine grained checks.. e.g. "check only the 'email' field for errors (on change) by hitting something like /register/email/some@email.com" i can see it done but it will result in a ton of code.. also.. if fields are interdependent (say we need to check password is the same) htmx requests dont seem to cut it. Maybe a little js is better here.
