What document are you referring to here?  This just describes how the
encrypted mailing list is going to work, not anything else.

But yes, we have had some "encrypted pdfs" be sent to us recently that
no one can decrypt unless they run Windows or do some really crazy hacks
with the gstreamer pipeline.  But that's separate from this specific
mailing list, we can always just tell people to not do foolish things if
that happens again (like we did in this case.)
