I had vehicle streamer in my drift server about 3 years ago and it was working fine.
I think that you are using it wrong, you should only use it interiors/virtual worlds as "Static/Actor/Unenterable" vehicles where if they can't be created its not a big deal.
You should keep working on it, but limit their functionality and make them only stream in if interior is used.
Tho, i'm not sure how hard is it, to make them work in plugin vs scripted.
