Electrical – Neutral (grounded conductor) for bathroom switch (NEC 404.2(C))

bathroomelectricalwiring

I understand that a grounded conductor (neutral) is not required by code (404.2(C)) for bathroom switches, but is there any reason that I would want to include it – future-proofing, etc.?

I'm going to rewire my bathroom soon (fan with light, vanity, and one GFCI outlet). The home run is in the ceiling, so I'd have to run a traveler to the switches in the walls if I want a neutral at that location.

(4) Where a switch does not serve a habitable room or bathroom
