A slow passenger is only a problem because of the low number of exit hatches. The bottleneck is the number of exits, not the slow passenger.

This is tested with volunteers before certification, see e.g. [3] for a video of the certification test for the Airbus A380. The details [4] are quite interesting: a third of "pax" must be over 50, three life-size infant dolls must be carried along, etc. Given those certification requirements, a slow passenger is very much a problem.
