Next is a patch to Dancer2::Plugin.pm to effectuate the use.

Shouldn't the Dancer2::Plugin.pm changes happen first?

The current (broken) Dancer2::Plugin.pm does nothing with this extra parameter and works like before. But see https://github.com/PerlDancer/Dancer2/pull/865 "We're currently trying to overhaul the entire plugin system. We have two competing implementations (one by @yanick and one by @veryrusty) and I hope we will be able to resolve them soon enough." That is very good news. I can stop working on D2 plugins and just wait.
