So, go into class D airspace as VFR traffic and see how close you are allowed to get to an IFR departure - the controller is required to give protection to IFR vs IFR traffic but in practice will try to keep VFR traffic away from it by issuing appropriate clearances.
It may not be what the rules say and traffic information is always subject to controller workload but it is what happens, especially at Brize.
When I am operating IFR there, I don't expect to have to take avoiding action on VFR GA because he hasn't seen me - I expect him to be kept away from me.
The FFS was to do with the fact you think it is 'rude' to be controlled in class D
