However, I though it would be "cleaner" to simply navigate straight up to the site-level object from the SEAccessProtocol object and extract the SiteUniqueID from there.
Are there circumstances where this wouldn't work? (assuming people are publishing valid information)
In this particular case it wouldn't work if one site were publishing an SE belonging to a different site - not normal perhaps, but not necessarily forbidden. Similarly you are assuming that one site tree (at the mds-vo-name level) only publishes one gluesite object. In the general case that would obviously not work, for all the other high-level objects (CE, SE, Service) you can have several of them; for the site you usually only have one but again it's not clear that it's forbidden to have more.
