Follow-up Comment #1, bug #52914 (project lwip):

You're right for standard routing. Currently it seems we would forward all
multicast packets to the default netif (unless they were received there).

However, currently, devices have the possibility to implement correct
multicast routing using the routing hook. Your change would remove that.
