Ok, great. Regarding the VoP code, I think nothing stops you from reusing
anything you find useful in there and build on top of it, but we should
consider it as a new submission then, which means that you are free to
change the interfaces without worrying about backwards compatibility.
On the flip side, this also means we need to carefully review the interface
to make sure we can cover the requirements of as many users as possible
without adding too much complexity for cases that we do not care about.
