The trouble with this line of argument is that way back at the beginning
of the CAB Forum in the middle of the last decade, we had various
troubles of this sort where CAs said "well, people keep embedding our
roots and then coming to us and expecting certificates, so we can't do
X, Y or Z because otherwise they'll be in trouble" - i.e. exactly the
same problem, and yet here we are in 2016 and it keeps happening. How
can we dissuade people from this idiotic behaviour? It seems like CAs
haven't managed to educate them (if they've even tried). One starts to
think that only if this course of action becomes painful and expensive
rather than grudgingly tolerated will word get around.
