Probably not.
Here they leave a small (about 3 meter long) gap

I mean : you don't add a "no-turn-left" or "no-turn-right" restriction

Well, usually, a "no-u-turn" restriction is indicated at
intersections. The relation "restriction" in OSM is also desgined for
intersection nodes.

In France, a solid line means do not cross. It is more than do not overtake. On
French motorways, the line between the main carriageway and the hard shoulder
is broken for this reason.
In this case it does mean no U-turns, and a left turn restriction will fix the
problem.

Hi all,
Someone on the help site is questioning about a missing u-turn
restriction on a roundabout junction with splitter islands ([1] in
French). The problem is when you take one roundabout exit and want to
come back to the roundabout, a router like OSRM is telling you to
immediatly turn left aft
