Personally I find this insufficient, at least as long as

and GPG inherits trust on these signatures as it does for all others.

Do you intend to give a "sig!1" to everybody who ever answered to an
encrypted e-mail you sent to them? They all prooved that their e-mail
address is valid.

That is the big danger I see in calling a service that signs allmost for
nothing a "CA". It devalues the real CAs that do check the identity of the
signed very thoroughly if they all get mixed up.

ct magazine and DFN-PCA have strong policies about this (at least for those
I have read them). 
If one begins to treat them like any homegrown e-mail validation service, it
may ruin all the good they have done to build up the strong web of trust we
have now.

Sorry, I don't undestand what you mean by this.
Is there something formally incorrect with my mails?
