Hi, is there any way to handle user already exist error in supabase?

This was removed in a recent update which was due for security reasons, but myself and others have voiced that security by obscurity doesn't feel like the correct approach for this and we prefer when the supabase told us the user already existed. The GitHub issue is here https://github.com/supabase/supabase-js/issues/296

Thank you for pointing me to this!
