Even if the next GnuPG version allowed to do that it might be almost useless 
if the older and other implementations do not show it (cannot show it at all). 
But I don't know how they react to such a signature packet.

Notations can be seen (and set) in old and other implementations (are not 
shown by default, though).

However this may be done: It makes sense that GnuPG prints a hint/warning if 
such a standard notation is used even if notations are not shown.

How is this a problem? Does it matter for that purpose (or any other) how a 
signature is encoded (does "text signature" mean --armor?)?
