I disagree with premise of this question. I don't think it should work for  
all users.

If the link is in alternative content, then by definition it is intended  
only for users who cannot see the picture, e.g. it could be a link to  
longdesc-type of page that contains no useful information for sighted  

The link should be inaccessible to sighted users in the same way <img  
alt="text"> is inaccessible.

An author who wishes to make link available to *all* users would be  
required use <a> outside <picture> (e.g. <figure>).

This could be defined as authoring error, and act the same way as

The spec should require that such elements (and any interactive elements  
in <picture>) don't interfere when image is displayed. I presume they  
would behave the same way as in an element with the `hidden` attribute?  
(speak:none, display:none, refuse focus)
