In the case of secure browsing at authenticated Web sites, I want to be
conservative in what I accept.  If a CA is generating certificates that
do not comply with accepted RFCs, what else is that CA doing wrong?  In
other words, if a CA sends CRLs that are not binary DER, that should be
a red flag that the CA might not be trustworthy in other respects.
