#error "This keyring needs some more work (see TODO)"
/* TODO
*
* This keyring needs some more work, so it will be disabled until its quality
* was raised. Some of the pain points:
* - throws a lot of g_warnings
* - it doesn't notify about some backend faults (like access denied), some of
* them are not handled at all
* - it could use libsecret's Complete API
* - code formatting could be better
