going down the route of ‘pastoral flexibility’ could lead to the Catholic Church falling apart in the same way as liberal Protestant denominations

Too late. That "pastoral" approach has been in full force since Vatican II. It's just that some are finally wising up to it.

That recent article, I’m sure you read, posits that the Church could go the way of Judaism; the Orthodox, the Reformed and I forget at the moment, the third divide.

This prediction seems to make the most sense to me, in the long term.

The Catholics could be or would be either Orthodox, Traditional, and Progressive.

It seems doubtful that the Catholic Church as a whole would simply devolve into one more Protestant denomination. No, the true Church will always be, even as Benedict XVI suggested- a smaller, but more devout Church. (something like that.) I would call that remnant Church, THE Church, but “Orthodox” might be it’s name. What do you think?
