Zinc indeed will continue to push in the simpler and more minimal
direction. Down the line I'm open to trying and benching a few
different ways of going about it with dynamic patching -- something
that will be pretty easy to experiment with given the lean structure
of Zinc -- but for the initial merge I intend to do it the way it is,
which is super fast and pretty straightforward to follow.
