I have as well. 4 different late models. The coils didn't drop right out after you disconnect the shocks.
I just put new coils in mine 2 months ago. After disconnecting the shocks, spring tab, and having a 200-lb buddy stand on the hub, a spring compressor would still be required to get the coil past the bumpstop and spring perch. Or, at least a pry bar. They certainly will not "drop right out" without disconnecting more than the shocks.
...but I've already mentioned that. Maybe the ones you worked on had worn out bushings?
There's a video above that shows the procedure. Watch that video and tell me at what point after he disconnects the shocks that the coils "drop right out".
EDIT: Here you go:

He has the shocks and swaybar disconnected at 1:32.
Seriously. If I'm wrong here, please show me the evidence that they "drop right out" after unbolting just the shocks and spring tabs. I can only go by my experiences, and they have shown otherwise.
