In GpgOL I would like to roll out the tofu support more and I think that for this I need to change the trust model to tofu+pgp just for mails. This would also give me the freedom to roll this out without changing global defaults e.g. for Enigmail. Basically I would like to have it configurable in the MUA if trust-model tofu+pgp should be used. This should not change the default for the system.

For file operations with Kleopatra I would still like to use trust-model PGP as I can't find a better user experience for files with tofu trust mode.

Something like gpgme_set_trust_model (gpgme_context_t ctx, int trustmodel);
