At least the project use nullable, which is great, but there seems to be some warnings, that'd be lovely if resolved (should be the standard for all new code).

Overall, looking to clean up any and all "leftover" bits that are either not needed/used/for this source and keep the test reflection as flexible as possible so we can refactor components one by one

We'll still need to adjust some thing as we move them around (such as WCEnumNameAttribute vs the System.Text.Json equivalent we'll likely move to, BaseRendererControl references, etc).
