I was think that forget.
In truth, most traditionally available solutions for "is the aircraft accelerating quickly enough to take-off" rely either on approxoimations or increased crew workload (at a time when they are too busy to have a relaxing cup of tea already)
One reason for this is the absence of digital information in the cockpit of runway remaining (except by making the crew look out of thw window).
The introduction of some of the next-gen ATC technologies could provide a means to fill that gap in data. However to absolutely and completely provide a total solution it would require either additional kit and workload at the airport end, or additional kit on airport and aircraft. So either way it would be expensive. So I don't see it happening for a while (although the introduction of next-gen at short & difficult runways could be combined with tower involvement to provide an additional warning for the most difficult cases)
