I still think that this stuff is the wrong approach: wireshark should
not need root privileges and if you want to make sure that the program
isn't run suid then it should check and pop up a notice that this is no
longer necessary and should not be done (and I don't really like that
approach as well, but it's way better than the proposed solution).s
Also, how do you intend to handle the case where someone starts
wireshark with sudo and then wants to read a capture file that's owned
by root and cannot be accessed with users privileges?

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