In the definition of ASDA and TODA/RA is a leeway to cater for this chit-chat you point at
Not to any great extent, other than for ASDR post Amendment 42 .. and even then we are talking about fleeting moments ...
The mantra - "if we aren't already stopping by V1, then we're going .." has a lot to recommend it on ASDR limited runways for the very great majority of events.
Even then, the 2 seconds built in for later certifications is a VERY short time interval if you want to talk things over. A prudent operator will have a fairly rigid SOP trying to minimise time while maximising crew effectiveness ..
