Right, that is the case for OpenPGP messages. But after all gpg-agent
decides what to display. The gpg-agent command SETKEYDESC is used to
tell gpg-agent about the OpenPGP properties and desired operation of the
requested key. However, gpg-agent may eventually be changed to screen
that information for correctness. This is in particular important when
gpg is used via a remote socket.

Conceptually it is not allowed that pinentry is used by other software
than gpg-agent. Today gpg-agent is mostly used within the same security
boundary as gpg (under the same user and on the same box) and thus there
is no enforcement of it. However, using a SE-Linux it is possible to
enforce that even on current systems.
PINENTRY_USER_DATA was implemented to allow the use of a web interface
