This seems unfair towards CIDER. Cider has excellent debugging, stacktrace navigation, integration with other tooling and more... that isn't available in Calva.

I would never say that you can't use Calva to get work done, but CIDER has a good deal more than what Calva offers currently. I could accept that maybe "99% of users don't need what CIDER offers", but saying that Calva is 99% of what CIDER offers is just completely incorrect.
