Touching the system partition isn't the only thing one would do with root. And if the ROM ships su in the ROM, there's no problem of being out of sync with upstream or even not passing boot verification.
It does open up an attack surface against the app that provides the UI to gate root access. But that has to be considered against the "availability" arm of the security triad.
Regarding the system partion and verified boot, it's the fact that it isn't the only thing one would do with root that breaks verified boot. You totally could package su in the ROM and ship it, but if a user installs something else to the system with it, it is very likely that the verified boot hash would change, unless I'm missing something.
