Maintain integration testing recipes in this repo?

In pangeo-forge-recipes we have an examples/ directory which contains a functional feedstock, which is in turn used for integration testing.

Here, we test against an actual GitHub repo (pforgetest/gpcp-from-gcs-feedstock). I wonder if we should abandon this in favor of maintaining test recipes locally in this repo?

I ask because it's feeling a bit tedious, and opaque, to me to need to update an external repo when we want to adjust what is tested. (E.g., for #139, we need a dict_object test case, but that will not actually be part of the PR, because the test case will end up in the external test feedstock.)
