You're talking about "issues" that are specific to one CA and that can 
only be solved by violating the BRs, right?

https://crt.sh/?caid=6471 has only been active for a few months, so it's 
been in scope for the BRs from day one.  I would expect the Forum to be 
extremely hostile to any future request from Comodo to violate the BRs 
for the benefit of Western Digital!
