This is an interesting suggestion.

I wouldn't mind putting it there, although I still prefer it to be
under glance for historical reasons and because Glance team knows that

How would it work if this lib falls under Block Storage program?

Should the glance team be added as core contributors of this project?
or Just some of them interested in contributing / reviewing those

Thanks for the suggestion. I'd like John and Mark to weigh in too.
