It is possible to share non-exportable signatures between private users.
see --import-options import-local in gpg(1). I know there are GnuPG
users who prefer to avoid having their keys on the public keyservers
entirely, and who are willing to accept the costs of doing manual key
distribution using non-exportable certifications.

those keys will not be accepted by anyone as valid, and users will have
had to jump through hoops to create them as such, so they know what
they're getting themselves into.

Nearly every key created by GnuPG in the last decade has had the
no-modify flag set. There was never consensus about exactly what it
means, or how to interpret it: does it mean that keyservers need primary
key approval before publishing a third-party certification on an OpenPGP
cert? if so, how does the primary keyholder express that approval? And
no keyservers ever implemented it, because there was no unambiguous
mechanism *to* implement.
interpreting it to mean "do not publish on the keyservers at all" would
mean almost no keys would be on the keyservers.

We have that already. It's having the "exportable" subpacket included
in the certification, with the content set to 0, meaning
"non-exportable". That's what i'm trying to do.
