Do we really need pcapng if multiple interfaces of the same type are specified
or is this "only" to make it possible to see which interface the packet was
captured on?

I don't quite agree with this: any has a very specific meaning and will (normally)
create pcap output, while your proposal would create pcapng output. Also the linux
cooked capture type does not contain a L2 header. Maybe adding a new "all" pseudo
interface would be better.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
