+1. I had stumbled upon this when working on identity support. I had
the same initial reaction that it's confusing. But soon I got used to
it and any other option wasn't improving the situation. AFAIR, all the
4 possible combinations of those two booleans are possible, but I
can't remember what could recurse = false, recursing = true mean.
recurse = true, recursing = false happens at the start of the
inheritance tree. recurse = false, recursing = false; maybe for a
table which isn't part of inheritance or partition tree. recurse =
true, recursing = true happens when working on a non-leaf non-root
table. If we could find out the impossible combinations and then unify
these two booleans into a single enum variable, that might make code
clearer - at least we will know which combinations are not possible
and which combinations are.
