It's presumed that it was just forgotten about, and OK to update.

Given the related PR has been merged, I suppose it's OK to close this issue. Please reopen if I was wrong.

I see as_api is still not present. Not sure about what else should be there.
Maybe I should rename this issue to just point out AS api.
Hopefully while fixing it, we'll realise if something else is missing.
