With “sharing” of the Apple Card in family can you get a second physical card?

This is all Apple says so far about sharing:

Set up Apple Card Family and add users https://support.apple.com/en-us/HT2094

It doesn't mention physical cards in the family document but right now you can get one if you have an Apple Card account:

Apple doesn't like us second guesing them here but frankly since you can get a physical card now and for other credit cards I have used you can get copies for others sharing an account, it would not surprise me if it will be possible for each user to order one.
