I agree.
I think that routing via instruments/samples would be better than routing via tracks (like now). At least in most occasions.
I was actually about to make a thread about this. Changing this could be pretty radical tho, for backwards compatibility and such… Personally I wouldn’t mind, but some others might. Maybe an option in the prefs could solve this, where you’d select between the “track routing (old Renoise mode)” or “instrument routing”.
I also proposed some kind of a compromise with routing options, so that you’d have some benefits of routing via instruments/samples in the current Renoise routing system.
