Should all urls be interpreted as route names or relation IDs?

[dittaeva]

I've noticed that the google bot has been accessing route.is/vec/vec/skgduorrhyfnzu.html and the same for every language. As I do not think we there is any link to such a file on route.is it could seem to be some URL check they do?

Anyway this bring up the question if all URLs that do not match a route name or route ID should be sent to search. Perhaps urls ending in .[whatever] should send to a 404?
