I see your point now.
Once again, I don’t know the internals (or ruby) enough… but there’s no way to know if the field name was provided on that request? Not present at all, don’t touch the name field of the account. Field name provided, set it (if blank, clear it). Wouldn’t this respect that protocol/behavior where only the provided fields are synched?
Sorry if this makes no sense — just trying to grasp from what I understand.
