  • Should CAN receive traits block until a frame is ready?
    • Can work this out separately if CAN is removed from e-h proper, since it's no longer a blocker for 1.0; perhaps an "avaialble" or "peek" method.
  • Roadmap to embedded-hal v1.0, what's missing?
    • Issue is more or less up to date, not much now! Perhaps a beta.1 release after outstanding PRs are merged
