I would guess just because it was inspired by earlier code that did much the same long before the link-pair extension ever existed, and it just hasnt been used by anyone wanting to do link pairing (which isnt that widely used; referenced by some other extension specs that..).
The protocol spec won't cover this as it is essentially an arbitrary choice in its eyes and indeed for most use cases (unless, say, you try to do link-pairs). What it definitely does say is that you dont need to populate the field at all for the typical 'simple client end' terminus of a link (from memory there is also a c&p error in there when it covers this, in terms of its references to source/target). I expect the existing options don't let you set the 'local' source/target address since the other side is usually the important one and set implicitly most of the time, and also more so just as the options classes are used in common for sender/receiver creation and so allowing that would mean one of them can easily clash with other configuration and perhaps need additional validation added, e.g clashing with whats set implicitly, or e.g with a request for dynamic that forbids setting it.
