You can do it by getting the last hri for that table , and getting it's
tablename. So it would require a meta hit. Expect an update soon

It is no longer possible to go from just a regionName to a tablename without a
meta hit. I could implement the metahit?

You can't without a meta hit.

Correct, these three reviews are tied in a certain order. They could be
combined into one patch to work, but they are easier to review on their own
imho. I'd be glad to combine like the first review.
