Then make it optional or give fine-grained control over it. When you get a new card number, you should get a list of merchants that have recurring payments on the old one, and get to choose yes or no to transfer each of them.

It'd be nice, but almost nobody does that. Wish they would, obviously, but there's apparently no market call for it.

There are other considerations in picking a card, though, and I'm generally happy with the overall experience with Amex.
