Asked about this in IRC, but wanted to bring it to the list. For experimental plugins, do we need to abide by the backward compatibility rule in a stable release? Same question probably applies to ts/experimental.h.
My opinion at first was no. It's experimental, duh! But the more I think about it, I think it does apply. We want people to feel comfortable using these plugins so that we get testing coverage and then we can move them to the stable directory. Thoughts?
