Of course yes it would be the best solution to resurrect that draft

Presently, OSM takes little care for road security, especially for children.
And it's not a good reason to neglect the existing kitchen because there
are no eggs.
I have mapped a number of 30km/h zones.
I was literally abashed that, among all the zones mapped in Belgium,
Germany, France and Netherlands, not a single one indicated a school
zone

hazard.
I stopped my mapping because I don't like to redo everything correctly
later.<http://wiki.openstreetmap.org/wiki/Road_signs_in_Belgium#school_zone>

The problem, as with most traffic signs, is that they are not located
where the problem is and that, as I see them used, they do not even
indicate the direction to where it is.
As well as duplicating other information albeit the word "duplicate" is
spoken as an OSM sin.
GSM software is perfectly able to draw most traffic signs on the screen
without an added element.
