This is a common mistake, intriguingly often happening in discussions around 
free software desktop implementation sharing.

In any case the single-sign-on will be implemented through a desktop 
service, , e.g. gnome-key-ring, kwallet module in kded, etc., which means it 
will have to have a well defined IPC API anyway, most likely D-Bus 

Which also has the nice side effect that it can be implemented right away, 
i.e. as a second interface to already existing key storage solutions without 
needing to simultaniously transition all applications using the desktop 
specific interface right now.

It would be a dependency of one service implementation, an implementation 
detail, so definitely not a problem in this context.
