Our tier levels also have varied platform support, can include tests not already grouped in a tierN_x, and can run previous tier tests with different flags. So it is important to note that after this change if you refer to "tier3" testing and I refer to "tier3" testing then we are not referring to the exact same thing.

Noted. This asymmetry is unfortunate, but it does not directly affect this work, I think. If we care enough to sync those up, then since nobody outside Oracle can guess what Oracle's definition of "tier2" and "tier3" is, it seems reasonable to say that the onus is on Oracle to match their definitions for "tier2" and "tier3" with the public test definitions, as much as practically possible.
