No, this is even required on some "wired" connections. For example Matthias 
Schiffer was against a change to remove rebroadcasts from the incoming 
interface when it is not a wifi interface. He requires it because his fastd is 
using non-wifi (so it basically a wired) interfaces. But it doesn't take care 
of any broadcast distributions for data which is incoming. He is relying on 
the fact that broadcast/multicast data he sends from a client to the fastd 
server is automatically rebroadcasted back once to the incoming interface. 
This will then force fastd to send this data to all its clients.

You also don't know what is actually behind the wireless device. So you can 
easily build a setup (yes, I have already seen this) which has a non-
transitive ethernet to ethernet-like bridge device which attaches via a second 
ethernet to the unit running batman-adv. Not rebroadcasting here would again 
create missing broadcast problems like with the standard wifi hidden node 
setups.

Kind regards,
