Charge: I've always felt that is a drawback with the AH limitations, that the strafer -C is allowed drones.
Grendel: I'm sorry but you're wrong on that one. Ju88s and most LW dive bombers made near vertical dives. The vertical racks used to store the internal 50kg bombs (slung upside down, by the way) won't function in a near-vertical dive, as they are perpendicular to the ground. Also, dropping them at low altitudes would not be effective, as 1) they are too small a bomb to use on specific targets, 2) they flutter, flip around, and are meant to scatter when dropped flying level [thus negating the accuracy that dive bombing gives you], and 3) the system just wouldn't drop them while diving.
Edit: Oh, and dropping them after pulling up was more spray-and-pray, inaccurate, and about as reliable as dive bombing lancasters in-game now. You make it sound as if it's precision-guided LGBs, but in fact it's more like a farmer scattering a handful of corn into the dirt.
In AH bombs fly through the plane (no impact) so you can dive bomb with internal ords, but you could not in real life. Not with most planes. That's why the Ju87 and many "dive bombers" had trapeze release mechanisms, to swing the bomb clear of the aircraft and its propellor.
