At risk of seeming condescending --

There is no such thing as a known-plaintext attack on GnuPG.  There are
only known-plaintext attacks against the algorithms in GnuPG.

Since there are no practical known-plaintext attacks against any of the
algorithms in GnuPG, we can conclude this feature does not facilitate
any such attack.
