Yes I am very aware Melbourne metro route numbers are on the cusp of being replaced with alphanumeric, but it's nowhere near ready in most locations.

Therefore I dispute this resolution as the data is supposed to be a representation of what is there, not what will be there at some unspecified future date.

* there are no "A60" signs between Westgate Freeway and Narre Warren.

* this route is widely signposted ALT-1 as of March 2022

* there is no known date of implementation

I was actively involved in the NSW alpha changeover, and those route numbers were not changed by the OSM community until the signs were up and visible.

Same goes with SR3 being changed prematurely to A50.

Changing these early only causes widespread confusion. Imagine people using navigation apps, etc.. and the route numbers aren't matching what is on the actual signs.
