Can we skip-tree the older versions rather than the newer ones? I find it more useful to consider what's holding us back from upgrading vs. tracking where we're already on new versions.

There are several issues with TestSys 0.0.7 due to our change from openssl to rustls. This includes base64, serde_yaml, thiserror, json_patch and possibly others. Is it worth explicitly calling each one out?

[bcressey]

It seems fair to assume that testsys dependencies will be as current as possible, if we're following the same methodology there, so skipping the tree here makes sense to avoid duplication of effort.
