You can only force everyone on a project to use a formatter if you are the one who has the authority to decree what will be done on the team. OTOH, if you are but a team member and you join a team where the manager does not think common formatting is important, then you get f*ck all.
So being built-in, idiomatic and expected cannot be over-appreciated.
