It's not hundred of hours of developer work to change this.

If the renderer programming is up to scratch then it should be able to automatically accept changes like this.

One of the programs I have done some development on has this built in.

In the case of amenity=police.

The program scans the icon directory for all icons on start up.

Before rendering it then checks to see if it has a matching icon to amenity=police.  If it does then it renders that icon, if not then it renders the parent icon, ie amenity.

If it's changed to emergency=police_station

The renderer does not require any change, the only changes required are moving the amenity=police icon to be the emergency=police_station icon (which is a 30 second job) and creating an appropriate emergency parent icon (and there's probably something already there we can use).

The program code to do this is approximately 100 lines of c including white space and comments.
