Can we talk/ask questions about UdonVM internals here?

Are we allowed to talk and and questions about udon vm internals? Aka the included .dll for udon vm, or udon is not that open? As I see that vrchat team included symbols too, so it looks like they don’t want to keep it that private?
As analyzing UdonVM internals is helpful for writing custom compiler (as we didn’t really get any full documentation, like list of externs and exact naming rules), but also generate few questions about some parts of that internals and I wonder if there is any chance to get some feedback from vrchat staff about it or sadly its not allowed?
