The signatures feature has been "experimental" since Perl 5.20 (May 2014), but expected to stay. After 8 years I'm ready to take the risk :) Have added Perl v5.28 (June 2018) as the minimum requirement, even though the current revbank should work with 5.20, to see if this bothers any users. Perl v5.28 is in Debian "buster", which is now oldstable.
