Comment (by acute):

 > If researchers need to change parts of a model that cannot be configured
 using the OnionPerf command line interface, they will have to change the
 OnionPerf sources to do what they want. I'd say that that's still easier
 than editing a TGen XML file. If the missing piece is better
 documentation, we should provide that.
 That is exactly what I had in mind for doing this.

 parameters like initial pause, transfer count, or filesize as part of
 #33432;
 >  - develop a ping model as internal model where OnionPerf generates TGen
 files, plus analysis and visualization code, as part of #30798, assuming
 there's need for developing such a model; and
 >  - remove the `-m/--traffic-model` parameter from the codebase and close
 this ticket as something we considered carefully but decided against.

 This all sounds good, but I'd add to this writing some documentation as
 proposed above.
