I’m also currently taking a proposal through a (second) RfC. Technically, it has been in RfC for a couple years, since there’s no process for ending the first one. Fortunately, the pages it affects have been quite stable, yet it also cites actual usage statistics in the database, which are much less stable.
When I first drafted the proposal, the tagging style I wanted to defend was more common on natural=peak than it is today. It’s still common enough on other kinds of features, but this has made it more difficult for me to find examples. There was even an active effort to eliminate this tagging style, technically during the RfC. It was a bit frustrating, but ultimately it was my fault for taking so long. At least it was an opportunity for me to raise awareness of my proposal.
If you haven’t already done so, consider adding a link to your proposal on each of the pages that would be most affected by the proposal. Then, no matter how the status quo should be documented, mappers can see that some changes may be coming soon.
