I have met one in practice: to override an invalid list on the key
itself. The key in queston was generated with PGP and said it supported
IDEA, that being my algorithm of first choice at the time I used that.

However, the key owner could not read my message because she had
imported the key in GnuPG (done by someone else more computer
literated), did not have the idea plugin installed and also didn't know
how to do that or how to manually change preferences on the key. So I
had to override locally.
