yes, but that's also what the routes do in the real world: they only
make half a turn. What is exactly the problem? The routers for
instance should be able to deal nicely with a roundabout that is made
up of 2 or more smaller ways. (I am aware that not all do, but this is
less a data problem IMHO).

if the route is correct before you split the roundabout it should be
no problem even without local knowledge to adjust it after you split
the roundabout (you can see where the route enters and leaves the
roundabout from the route itself).
