As I understand (from hearsay) the argument has been that in order for MCC to be feasible, it'd have to retail at a price that the market is not willing to bear. I can only guess at what kind of level this would be, but probably north of Ilford MGWT. If this is the case, I suspect that argument is pretty solid and it would take a looooong time for a batch of MCC to sell out.
In the final days of its production (or in fact, just after production had ended), I bought it from time to time because it was pretty much always on clearance sale. Apparently the retailer I bought it from had much difficulty getting rid of it.
Keep in mind that paper is a niche product. Film is a decent seller, but given how preciously few people actually darkroom print their negatives, paper just isn't a very attractive proposition.
MCC is/was a gorgeous product, that's for sure.
I don't think that compares to MCC in several ways, really. It's also a nice option to have, but very different.
