Meh. It's not uncommon for people to have multiple keys that they
ask signatures for during keysigning parties. But yeah, that this
is more work is the obvious downside of this approach.

To be fair: I encrypt all of my external media out of principle
anyway, I didn't just do this for my GPG key.

Furthermore, security by obscurity is rightfully frowned upon
because many people use it as their _only_ security strategy. But
here it's just use as an additional barrier to something that
actually has actual security properties.

I didn't mean to imply that you were. ;-)

I was just saying that's kind of the only kind of scenario I could
come up with where someone could indeed upload a private key to a
keyserver by accident.
