This sentiment seems similar to my own considerations with regards for
need to change. If we are to change, lets do it right, not just some
small nitpick, in particular with regards to removing some complexity
since it is breaking backwards compatibility anyways (I'd propose e.g
getting rid of trust signatures for V5). The most common complaint I'm
hearing about OpenPGP is that it is too complex, as such I'm beginning
to change my mind as to whether protocol agility is only a good thing,
maybe we should work more on getting to consensus and reduce
implementation complexity in order to make it possible for better
auditing of implementations etc.
