I don't suppose you could write a version which just returns a vector of
strings, could you? (Such a version wouldn't have to change when/if we allow for
array Vars.)

I thought about that. I really wanted to rewrite the existing code to return a
vector of something (strings? string pairs?) and have the webui code convert it.
But that's more code overall, and it seemed stupid for the webui code to have
this big dynamically allocated structure created, and then have to be re-created
in another format. For us, we only want the non-localized name, which means we
have to do some conversion anyway, so I figured it's best to keep the current
code as Values and have us converting.
