It looks like you are changing the semantics of this bucket.  Is that true, or
are you simply clarifying what the semantics were all along?

Latter. I changed some existing labels just because they were not clear on
semantics or sometimes misleading, so to adapt the current usage.
New ones are added to set precise status code for more situations.
