You don't really need authority to propose changes (e.g. send a patch). 
I guess you might attract sharp words from a maintainer if the proposed 
change were conspicuously reckless or extremely short sighted ("my use 
case is the only one that really matters") but I don't see any risk of 
that here.

Think of it like this: if folks with @arcticsand.com mail addresses 
don't try to document the vendor prefix, who will?

Personally I'd add it as a new patch but I'd make it the *first* patch 
in the series.


Daniel.


PS Top posting *is* something that will eventually attract sharp words
    from some maintainers ;-)
