Not sure I agree.
Having to press a button to proceed would be incredibly annoying in stop start traffic.
Yes, to be fair it does get annoying at times, but still preferable to the car "suddenly lurching forward" because someone has forgotten* they've got adaptive cruise on.
Most implementations of stop/go allow 20-30 seconds stationary before requiring a manual intervention, doing it immediately sounds not that well thought out, on the basis stop/go systems are linked to safety, so if you make it inconvenient/unworkable people won't use them.
Note, Tesla keeps activated for a long time (I've never experienced it actually disengaging in any stop/go traffic) which I think could be improved..
Hell, I was driving a manual van the other day with adaptive cruise, it let you change down/up as needed without disengaging and I'm sure I wasn't dreaming when it (from my recollection) even allowed some trail braking when over speeding without disengaging the adaptive cruise, I actually remember being surprised when I took my foot off the throttle in some situations and it started speeding up after I'd changed gear and/or slightly braked.
This is why we need data across the industry, we have so many cars around that data should show what does/doesn't work and whose hypothesis are right/wrong..
Agreed - probably somewhere in the middle would be the best, I don't recall regularly being stationary for more than 10-15 seconds.
That being said, I rarely drive in stop start traffic, so quite probably if I did more so then it would affect me more
* although arguably anyone who does this probably should take the bus...
