At the time, the last evidence of maintenance was adding Perl 5.26 at the end of 2017, and there was no evidence of anyone fixing bugs since 2011 (several of which have yet to be fixed so far, and many new ones now added, but we'll see what the next iteration brings). The revamp work was entirely unknown aside from vague promises of "an update" until last week; so until then I would have agreed with "moribund", and indeed that was the motivation for perldoc.pl, but that is clearly no longer apt.
