Isn't it the only real use of LWIP_NETIF_HOSTNAME option ?

Different hostnames for different netifs? That's not normally the way
POSIX-y systems work. Usually there's a single global hostname instead.
I'm not saying it's necessarily wrong or bad, just unusual.

I presume you have implemented something in the DHCP client that causes
this hostname to be passed in the DHCP request, and if the DHCP server
supports it, that will become the DNS name. That would be nice.

You shouldn't do anything. Whoever changes the hostname should decide
whether to do anything.
