This is awesome, thank you!
Yes I think there are a couple of minor corrections to make
but I haven't had the time to go do the research yet, so
hadn't yet responded.
Nothing is "supported" upstream anyway until there's a
system with a DTS that uses it, and that won't happen
until after the end of the merge window.
Again, thank you very much, it's a safe thing to take
for now.
