FWIW, I'm not a big fan of this, because it is just a variation of
tagging for the renderer, with no support by current rendering styles
to begin with. Routers should already have no problem with the data.

That said, I don't see a better tag that your style could use to
decide displaying that road (from your 1st example) earlyer. The
maxspeed is just 50 and there are only two lanes, that seems like weak
arguments for force early display.

What I'm going to say may sound beside the point, but I suggest you
simply ignore this as a non-problem. Leave the data and rendering
as-is :
* If the user asks for routing, the secondary road will be used properly.
* If the user is looking at a low-zoom rendering, he's probably only
interested in a rough idea anyway like "I'll get near Praha using this
primary road, and can probably reach city center from there".
* If the user zooms in, he'll see the secondary road.

See ? No problem to be solved :)
