I think that's going too far.

I believe someone might be able to construct protocols for secure channels 
using authentication/authorization provided by SPKI certs and that the 
(public-key ...) block should be able to describe an encryption key (or D-H 
key).  Someone might even want to define a (tag ..) field which declares an 
encryption key.  I would imagine that key (or its hash) to be in the (tag), 
not in the (subject), although I suppose that's open for discussion.  
However, if it's in the (subject) then we've opened up a political rathole, 
IMHO.
