One thing to add. PDF/A is being used by archivists around the world to
archive PDFs, and other document types for long term preservation and
access. I was I think the only one looking into using PDF/UA to improve
usability, as far as I know. So it is still a format that is used, but as
Philip mentioned UA is the PDF flavour for accessibility. A new version of
PDF-UA, 2 instead of 1, is actively in the works.

Cheers
