LR Intelligence: Stack shots based on time and overlap. Process HDR and pano accordingly.

LR needs to get smart. With a single command, LR could look at photo times and stack HDR and panos. It could then do feature recognition to determine if a shot has overlap [HDR] or if it's panning [Panoramic]. Done. Let me drink my coffee, come back and deliver my photography.

Indeed. See autopano from kolor for automatic bracketing identification and automatic panorama identification.
Unfortunately existing auto stack by capture time, doesn't seem to be able to use sub second information, so when I shoot a bracketed panorama (moving fast) it thinks some stacks have 4 some have 2, some have 16.

Doesn't it look for timing between shots to /not/ include? Like 
1 - 2 - 3 can be 0.001ms interval [pano] but if shots 4 - 5 - 6 started 1 second later they're not included in stack 1/2/3

my understanding is that light room uses the time interval setting you choose in the dialog  (1 second) to look at beginning of photo 1 and beginning of photo 2 and if more than 1 second elapsed it makes a new stack. 
Therefore when I shoot
bracketed burst 1 (night time so slow shutter)
1 - 0.0
2 - 0.6
3 - 1.2

4 - 2.2
5 - 2.8
6 - 3.4

it generates stacks
1,2
3
4,5
6


likewise if I shoot high speed with my 1dx
1 - 0.0
2 - 0.1
3 - 0.2
quick pan
4 - 0.8
5 - 0.9
6 - 1.0

it stacks
1,2,3,4,5,6

I don't think it works that way? ... try it? My understanding, using your example, is that 1-second would give you 1,2,3 and 4,5,6. Then for 1dx, you'd get them all in one stack as you have so you'd have to adjust your stack timing for that camera to be 0.5s. You can filter by camera and create auto-stacks for each camera. Just tried it. [not that it matters I guess]

The minimum interval for auto stack by capture time is 1 second

Ah! So they'd have to change that or you'd have to change your shooting. How realistic is it for you to fire off a second pan 600ms after the first? Are you forward then reverse panning? Just curious.

well I guilted myself in to collecting data rather than real work (ok I was already procrastign commenting here)

 lightroom only shows the seconds in capture time (see here where they say they use difference in capture time https://helpx.adobe.com/lightroom/help/grouping-photos-stacks.html#WS4FA9631A-25CC-43e2-B3E2-20FC80E... )
on a landscape panorama where I wasn't in a hurry because nothing was moving (where I was shooting 0, -2, +2) on a 5ds r with a slow buffer

autostack group 1
1 - 3:14:47
2 - 3:14:47
3 - :47
4 - :48
5 - :48
6 - :49
7 - :50
8 - :50
9 - :50

autostack group 2
:52

:52
:53

group 3

all of these exposure speeds were ~1/100th of second so provides no data on whether these use start or stop (and if they don't have access to sub second timing, then irrelevant)

I guess the fundamental issue is that I wish this set was bracketed by 3, so I could see the panorama in the grid, rather than being grouped in to sub batches. If I increase the interval to more than 1 second, say 10 seconds, since it's processing the entire folder, i starts to combine non bracketed pictures that aren't panoramas together.

The time taken to try different settings, and then get close then check and unstack (and change the stack if one is put in the wrong group) seems to add up to more than the time savings for me.

If I could select a group of images (without moving them to another folder) and run autostack on the selection, that would help some https://feedback.photoshop.com/photoshop_family/topics/lightroom_auto_stack_by_capture_time_use_curr...

also if they don't want to implement algorithm to try and figure out bracketing sequence (say 0, -, +, vs, -,0,+) ability to select a group of images and stack in groups of n

I was just thinking of this idea a few days ago as a way to remove grunt work. I'm in favor.
