I tend to agree that, which the Prefix of 'oxendict' should be "en" for
best usability, the Preferred-Value of "en-GB-oed" should be
"en-GB-oxendict" for best compatibility with the meaning of the original

The best part about this registration is that users like Michael will be
able to write "en-IE-oxendict", which was not valid with the registered
whole tag. That was a major reason why we moved away from registering
whole tags.

Since the original tag include the region, the preferred value probably
should too. The resulting tag preserves the most information from the
original so that matching operations that matched the old tag would also
match the new one. New users of the subtag can generate whatever tags
suits their application.

You can't have two Preferred-Values for the same deprecated tag or

mapping is.

The former, since that is the recommendation. Or both, for redundancy?
