I'm sure there are and will be other issues that are unfortunate I guess 
- key sizes, hashes, EKUs, CRLs, OCSP and much more...now where to draw 
the line?

In this case it's not a root (of Verizon) but an intermediate CA to 
them. I agree that there is some pragmatism as work and the forum, on 
the other hand this isn't all new to them either and has been on the map 
for a while (for both BIT and for Verizon). It's certainly a headache to 
them, but I have a problem with the browser showing "*admin*" as the 
issuing authority (not stating the various reasons now).
