Transcript links seem a lot more common than (say) D-links.

Has anyone ever come across a case of a publisher that refused to
include a link to a transcript because of design considerations?

This is trivial to fix with CSS:

     transcript a { position: absolute; left: -999999px; }
     transcript a:focus { position: static; }

Authors don't have good awareness of the need for visible focus, but
this problem is not particular to transcript links.

Maybe one could come up with a generic solution to this problem along
the lines of "display: hidden-until-focused".

But this would still leave the transcript with have poor discovery for
the typical (mousing, sighted) user. As these users want access to
transcripts too, I'd expect publishers to use visible links. Has
anyone ever come across a case of a publisher that included a
transcript link, hid it with CSS and failed to make it visible on
