Specials is a big deal, having documents with broken links, annotations
etc. is a no no for me, and I mainly do interactive not print documents.
The other main issue is the need to explicitly support every package,
so if some package I need is not yet supported by bidi, then I'm left
alone in the cold. Lastly, supporting implicit bidi (AKA Unicode bidi
algorithm is very crucial, since part of my need is to typeset documents
written in other markup languages (e.g. DocBook) and converted on the
fly to tex, so I can't manually mark RTL runs of text (except by
manually post-processing it, which is not an option). There are other
limitations of xetex unrelated to bidi, but that is another issue.
