Deprecating grandfathered tags redux

I don't understand this.  The existing subtag is 'oed', which is not a
valid variant subtag.  'Oxford' is only another proposal.

But, y'know, other than satisfying Mark Davis's rage for order :-),
I wonder what benefit is achieved by changing 'oed' at this point.
There are almost 2000 ghits for it, so knowledge about it has leaked out;
it is talked about, not just used for tagging.

Almost all theorems are true, but almost all proofs have bugs.
