There was an option that was never used, in that you could set your protocol tap as a first tab in the Conversations and Endpoint dialogs.

The command line option is still registered, mentioned in the autogenerated -z help and the manpage, and just doesn't work anymore with an log warning about the missing method.

This also removes the ability to launch the IOGraph from the command line, see #19042 (closed)

A problem is that the same registration function is used by the tshark CLI conversation and endpoints taps as used by the GUI. The tshark versions do want the proto id and the filter, even though it doesn't make sense to use them in the GUI. (As the GUI filter is always the main display filter, unlike other taps that can have completely different filters that are displayed in a line edit in their own window).
