Which is no different. That's exacly what happens when
"modprobe dummy numdummies=2" creates the two first interfaces.


 ip link add link wwan0 name dummy0 type vlan id 2
 modprobe dummy numdummies=2

ends up with dummy1 and dummy2 created by the dummy driver.

You are trying to make up differences that just aren't there.
