"Understud" is a pretty awkward name, but I'm definitely adding it to my glossary of "potential" names for that feature. "Underbar" would reinforce that it is about 2LU wide (like a Bar element), but that's not a real word either.
maybe even something as simple as "spacer" would be better?

Perhaps not, although "hollow" often refers only to those studs that are open on top but do not pass through the brick. (A stud that does would be "open", and there are also some that are "blocked".)
Very good point. I have seen both hollow stud and open stud used, and never put much thought to that difference. It's worth including in my analysis and discussion. (Both allow you to attach a bar element, so long as it doesn't have a rounded end.)
