Given that the multiple backend strategy only succeeded in replacing an existing backend with another backend several years later without achieving any of the interoperability goals of the JVM or CLR, I'm not even sure how to speculate on the reasoning behind that decision.

I'd say, it turned out to be more difficult than expected?

You haven't addressed my point that NQP yanking the rug out from most other languages running on Parrot harmed Parrot. That seems like a material concern.

I guess I don't understand how NQP would be yanking the rug out from other languages, technically speaking? That it could be seen as a vote of no-confidence: well such is life in the open source world.

You haven't addressed my point that I personally spent multiple months offering to make Parrot better fit NQP/PCT for P6 and was repeatedly rebuffed.

Not having been around at that time, I don't think it is up to me to address that point. If you were rebuffed, I can only surmise that interpersonal and technical relationships had already soured enough not to trust the validity of your offer. Note: I'm not saying that the intent of your offer was questioned.
