I do agree that there is perhaps a limit at which the pedantry gets a bit much, such as my own example of XC running via Stourbridge - perhaps not super relevant, and clearly including all avoiding lines would be overkill, however it does raise the question where the limit goes? - ultimately that is up to the map maker.
However when the map maker chooses to include for example, the Didcot avoiding line, Rotherham Central on its own little spur, as is done in this first draft map, its not necessarily unreasonable for people, based off of what shown on that draft, to then come with suggestions of other places where there is track geometry avoiding a place that is very seperate to the main route physically, such as the Ely North curve, or Sleaford avoiding line, or the quarry lines versus the route through Redhill, admittedly each of these having very different service levels. But as i say it is up to the map maker to set the parameters for what they wish to include (such as XC via camp hill, despite not stopping there).
Then the rest of us can of course come with suggestions, and as long as we are respectful about it, and don't go completely bashing someones hard, and very good btw, work done in their own free time, i don't necessarily see a problem with suggestions such as the Ely north curve. Its not inconsistent with what is already shown on the first draft.
