Why migrate away? Even if GnuPG 3 stops supporting RFC1991 there will 
always be GnuPG 1 and GnuPG 2 around to decrypt ancient data and verify 
signatures made decades ago. That's the beauty of Free Software. Nobody 
can take it away and since it's Open Source it will always be possible 
to compile it on new OSes (provided we will be able/allowed to install 
what we want on those OSes).

I fully understand that some people will want to migrate but I don't 
think an easy migration path should be one of the guiding design goals 
for a version not supporting RFC1991.
