I thought gpg already implements the MUSTs very well (ok sometimes
there are security problems but this will probably never go away with
any software).

He's still writing ;-)

Unfortunately I see a general trend to use the simpler but weaker
hierarchical model of X509.... :-(
Like the German national authorothy for digital signatures.... they
only offer X509.
btw: Some time ago I've asked them where I could met one of their
officials to securely get the root certificate...they told me that
this is not possible, and that the root certificate is only available
via an ldap server... LOL
(You must know,.. in Germany there are no man in the middle attacks,
so this is actually secure *G*)

Why? Just because new (perhaps incompatible) features are added in
newer versions,... nobody has to use that newer versions, right?
