kerb=* si può usare sui crossing senza barrier=kerb ("kerb=* is also used on a highway=crossing. This usage indicates that there is a kerb somewhere near this node that someone visiting the node might want to know about, but it does not imply that everyone visiting this point has to cross the kerb, so barrier=kerb should not be used on such nodes.")

Lo ripristino perché avendolo rilevato due mesi fa di persona penso la situazione sia rimasta invariata.
