I struggle to reply with the already complicated situation from your previous comment. I do get that there are similarities but to echo the marked solution:
It is not standard for the team to disclose why the removal (apart from the property owners’ request, and this seems only for clarity not as a criteria decision) is. We don’t know if the team even have liberty to do so further than what has been explained.
The examples visible to myself are for the routes as a whole which seems to be not what is being asked. The similar restoration request you added in that thread has a tangible reference to the specific markers existing afaik.
The link for the specific route of the removed markers you want to restore also is redirecting at an empty resource for me. So that might be the root of the problem.
Reading through the linked discussion, it also seems a habit of disruptive behavior. I do not want to incentivize this further. Please post the full nomination if you would like to re-appeal with new information in your own thread. It may be helpful to summarize what has already been established since it does seem complicated for me.
