None really, it's just easier to point the thing along the straight line between BPK and the EGGW overhead and give Luton App a shout. But we'll not go there again
More laziness than terror, which isn't a good excuse I know. But as you say, airspace busts happen for a reason, and class D is class D: VFR is allowed.
Also for some GA pilots transiting the Luton Zone is the only experience of proper controlled airspace flying they will get - it was for me before I flew abroad last year - so maybe asking for transit is not as bad from a continuous learning point of view.
