B 787
The taxi routes in this document for the B 787 use the parallel taxiway for its entire length both entering and leaving the runway.
It's not clear what has changed from the time when the BRS master plan stated that the 787 would be too wide for the parallel taxiway (wings would overhang a fence next to a pubic road) and suggested that turning circles would be constructed as an interim measure, with a longer term goal of moving the public road (Winters Lane) to the north, something that would doubtless have been met with howls of protest from all sorts of groups and individuals.
It does seem then that one potential operational impediment no longer applies unless someone with expert knowledge corrects me.
