There's always 'risk of having another bust'. I wouldn't stop the MEI for that reason alone. The most common checkride failure is actually the Initial CFI. If you busted the Comm oral, went back for the retake and passed, and have continued your training progression successfully, I'd say you have a good interview story, nothing more.

Interviewer: "So tell me about your checkride failure."
You: "It was on the XXX checkride. I messed up in the following way. Evaluating my performance, I learned that I should have done this differently. I incorporated what I learned, re-checked successfully. I learned from my mistake and haven't duplicated that error."

Even if you have more than one failure, as long as they weren't for the same thing, this formula works.
1. Take ownership of the failure (don't play the 'blame game')
2. Learned from the failure
3. Didn't duplicate the failure
