Lawyer tabs do mitigate this though, right?
That's not what they are designed for, but they can in some circumstances keep the wheel in place long enough for you to notice that it's about to be ejected.
and front facing dropouts. The latter is done to prevent exactly that right?
Yes, the forward facing fork end is a way to make the brake work harder to eject the wheel by forcing it to roll the axle along an inclined plane rather than just spitting it straight out of a complete void.
For anybody too young to have enjoyed the Usenet discussion of this subject back in the early 2000s, James Annan's essay remains available at https://diskbrakesqr.wordpress.com/
For rear wheels in vertical dropouts and anything with rim brakes, it will still be fine. People get away with Ti and even aluminium skewers on weight weenie bikes, because the wheels mostly want to stay in the dropouts and the side loads are small if you don't jump. The 5mm steel QR only has problems in disc brake fronts because the brake reaction is trying to push the axle out of the fork ends.
