[GraphHopper] CH vs A*, variable edge costs

Hi,

  so GraphHopper allows me to use CH or "classic" Dijkstra/A* routing.

I know that when using CH, you need a different routing graph for each
profile - e.g. car, bicycle, pedestrian etc.

But for the classic algorithms, this should not be necessary; e.g.
gosmore (which uses a variant of A*) can do a dozen of profiles on the
same graph. Is that possible with GraphHopper as well, or does GH
require separate routing graphs even in non-CH mode?

Bye
Frederik
