Per the XRD specification:

2.4. Element

The element contains a URI value that is an additional identifier for the resource described by the XRD. This value MUST be an absolute URI. The element does not identify additional resources the XRD is describing, but rather provides additional identifiers for the same resource.

(emphasis mine)

In other words, the alias list is expected to link to things which are not just semantically the same, but exactly the same. Old user accounts don't do that

This change should not pose a compatibility issue: Mastodon does not list old accounts here

The use of as:alsoKnownAs is also not quite semantically right here
(DID-CORE, which defines it to be used to refer to identifiers which are interchangable) but that's what DID get for reusing a property definition that Mastodon already squatted long before they got to it

This one is currently marinating on akko.erincandescent.net to see if we have any issues, but its a minor change so I don't expect any
