Hi Loc,

Great to see v8 of the patches :) A comment below.

nit: I expect you'll still get a little push back on that (similar to
last time) because it doesn't actually implement anything, so while it
is "safe" it's only because it's empty :) Might be better to indicate
that those are the features it is supposed to have when implemented.

That's great and seems to address the previous comment from v7.

Thanks,

Jon.
