I agree that 'highway=construction' should be omitted from routing. That to me indicates "they are building a road but it is not usable". If the default style routes over that, it's just a bug and should be fixed.
last time i looked highway=construction didn't imply access at all, leaving it to the mapper to set access= appropriately.
It doesn't explicitly, but there's a strong implication that highway=construction is for unusable roads - because construction=minor is for usable roads with construction activity. Quoting: For minor road-works (where the road in question remains open), use construction=minor (and don't use highway=construction, but leave it at its default value).
this makes sense, because sometimes construction is impassible and sometimes it's not.
repairs and resurfacing etc. are generally passable and that's what construction=minoris for. A new road that has been proposed and is now being built is essentially never passable. Or once it is, it's time to retag it has highway=secondary or whatever and add construction=minor.
unfortunately, the wiki doesn't really explain this and what mappers and data consumers are actually doing seems variable and inconsistent.
True, it's a mess like all things wiki :-)
