Both would be separately useful, e.g. "show me all packets that refer to
192.9.200.1 anywhere", i.e. "show me all packets that contain an FT_IPv4 field
with the value 192.9.200.1" could be useful, as could "show me all packets with
the Source column being 192.9.200.1".

Yes, but that might still be useful - as might, for example, having "host
foo.example.com", and perhaps even "ip.{src,dest,addr} == foo.example.com"
matching *any* of the addresses returned for foo.example.com if it has multiple
IP addresses.
