IIUC, it do this to be able to have a nice user interface when used
interactively, e.g., switch to the output buffer after decrypting
something, but at the same be usable from lisp code that do not want
pgg to do anything with the user interface.

Is that bad?

The number of uses can be reduced, but I'm not sure I see why that is
better.
