@openstreetmap , I get that rate limiting for the routing service on openstreetmap.org is required.

However, it would then be good to not fire a request on every pixel my mouse moves when I drag one of the start/end markers around :| .

I got 429'd by just moving the marker from one street to the other. I also only found out that it's a 429 because I looked into the devtools. The UI just says "no route found".
