Some time ago we discussed about how to deal with obsolete packages that
will be removed from pkgsrc in the near future.
Maybe it would be the opportunity to implement something like an
OBSOLETE variable, to be displayed when a user install or upgrades
to an obsolete package ?

something like
OBSOLETE+= "this package is EOL upstream and will be removed after 2023Q2"
