We will work on improving and refining it.

Wait, I thought this was going in because it was already part of the ABI not an experimental WIP. Which is it? :)

I'm also less convinced of the utility of this ABI extension and would like to hear about the appropriate discussions. I don't think I saw them on the list, but I could be mistaken. What's up here? What's going on with the use of gnu note sections rather than any other part of the ELF abi? If we can, I think there should be a longer discussion about both the motivation and implementation of this feature.

Thanks!
