Still it is my opinion that
I think it might be more accurate to say that Volker, who creates the VM, decided that he only has time to ship a full blown official Sage VM. If somebody, anybody, wants to provide (and regularly update) an additional VM like you describe, I don't see why we wouldn't ship it.
