I figured the easiest path forward is to simply leave the previews types for RequestParameters and EndpointDefaults but mark them as optional.

@wolfy1339 When you are ready to pull the trigger - I'm assuming you were waiting on this before resolving all of the other breaking change PRs - I believe they are all approved and are ready to be merged in the order specified here.

I'll take one last look at all the leaf repos to make sure - but we are g2g for merge on the node and this breaking change. Please let me know what you think.

Thanks again for all the work on this! ❤️

I'm merging this into the beta branch so it can be tested a little with the other leaf repos before it goes to stable.

Ah shucks! Forgot to add BREAKING CHANGE.
Good thing it's only the beta branch
