No, what was said at the relevant TPAC session wasn’t that specific.
It was just a vague repetition of the myth that HTML5 “doesn’t play
nice with XML pipelines”.

Polyglot markup is a bad method. On the input side, it limits the
range of input compared to just taking both an HTML parser and an XML
parser off the shelf. On the output side, you can’t use a generic XML
serializer, so it’s an illusion that polyglot would let you get away
with no HTML-specific software at the output end of the pipeline.

But we’ve covered the technical issues again and again. The purpose of
the first message in this thread is to serve Process per Chair
request—not to present any new information.
