Wouldn't it make more sense to not make dumpcap setgid but rather put users who
are allowed to use it in the 'network' group? (Or to do like the Linux distros
do and create a 'wireshark' group and make the bpf devices readable by members
of that group?)  That way the admin can still control who can run dumpcap.

dumpcap has the setuid option for systems which don't have capabilities (or bpf
permissions) which allow dumpcap to run without elevated privileges.
