I've orphaned the following packages:
cygcheck-dep Mikhail Usenko
cygextreg Joni Eskelinen
engauge-digitizer Mark Mitchell
polipo Alexander Georgievskiy
The maintainers of which have been inactive for a long time (no activity
since 2020), and didn't respond to my attempts to contact them.
Consequently, these maintainers' (long unused) ssh keys are also disabled.
polipo is unmaintained and considered obsolete upstream, and
engauge-digitizer upstream seems to have disappeared, so maybe both of
those are candidates for removal.
