@estebank also here's a draft PR for the subsequent PR that adds support for dumping feature status info: yaahc#3

I have this open on my fork because it's using this PR as the base branch, it's probably worth looking at now but I don't plan to open the PR until this one lands

Because we use dyn Error/IOError we don't display the file path that we couldn't open. That's not ideal but ok for now. Let's revisit in the future.
