Kleopatra shall not offer gpg's deprecated keyserver option in the GnuPG System configuration dialog (see T5462: gpgconf: Make gpg/keyserver option available again).
Old description (changed following discussion in this task):
Several options listed by gpgconf --list-options have expert level invisible which means "This option should normally never be displayed, not even to expert users."
Kleopatra currently lists all options (except in de-vs compliance mode). I think Kleopatra shouldn't offer invisible options in its configuration dialog, e.g. it shouldn't list gpg's deprecated keyserver option (see T5462: gpgconf: Make gpg/keyserver option available again.)
