No, the throttle is just as responsive in M-mode on 7AT as it is on a manual.

Delay on the freeway when stomping it in D? Not skipping gears when floored in 7th to a 3rd drop?
If you drive in D, it will shift down as far as it can given rev limits if you floor the pedal and hold it. There's always some pre-shift delay, but IMHO it's not really notable in the scenario.

Shift flare? Sluggish shifting when cold? Overheating on track-days without an additional cooler?
I've had occasional shift flare on the 4->5 shift recently, but I think that had more to do with cold fluid and/or me experimenting with strange Torque Map settings for the 7AT in UpRev and/or perhaps I'm slightly underfilled on fluid. In any case 5, 6, and 7 are all overdrive gears anyways. You get into the low 120's mph at the top of 4th when you're on the throttle hard. I could see using maybe 5th on a very fast track on an NA 370, but never 6 or 7.

It does need to warm up a bit if it's cold out and/or the car is overnight cold before it shifts optimally. And it does need an additional cooler for serious track use.

How does it feel in "manual"? You floor it and it's an instant connection like the stick, or the tq converter soaks up the "hit" and it feels sluggish from say, a 50mph punch compared to a manual?
It's a very instant connection just like a manual when it's in lockup mode (which is pretty much anytime you're not at extremely low revs, or not in the midst of a shift execution). For example, you can sit up around 4K RPM or whatever at maintenance throttle level and gently play the throttle up and down over the maintenance line and get very reactive feedback from the car shifting between slight accel and slight decel. And if you stomp it at that point, it's going to shoot off just like a manual would.
