The latest version of pip (which we require users to update to) uses the new resolver by default (yay!) so we can remove all the additions of the feature flag.

Anywhere you see it, remove it. With the docs it should be pretty straightforward. However, there may be some slightly more interesting code paths in .py files, there shouldn't be many though.

AC:

• Added example to CI pipeline

Allowing blueprints to export themselves as a single function decreases the friction of development.

Use case:

Blueprint = function(...) {
}

Internally:

if (typeof Blueprint === 'function')
  Blueprint = { name: Blueprint.name,  in: Blueprint }
