Isn't highway=proposed for this? I replied on the forum in more detail:

How does lowering the roadspeed work? Carlos Dávila suggested the same:

>Perhaps mkgmap:road-speed could be a good option:
>highway=* & construction=* { add mkgmap:road-speed = '-1'; add 
>mkgmap:road-speed-min = '1' }

How does this work? I did not follow the discussions when this was 
implemented, because my personal itch has always been bicycle routing.
