Right. As I understand it, the 'hash' is a representation of all the
features the client supports as it is currently operating (i.e., the
"base" features and all the features associated with various plugins and
extensions and so on). So AFAICS it doesn't make sense to force the hash
into the existing 'ver' or 'ext' attributes, since the meaning is so
different.
