If a C172 or similar decided they wanted to backtrack from that point, with or without asking, he would probably incur some form of displeasure and probably get delayed!
Backtrack from Sierra or Mike???

Its about time you started letting us depart 27 from Mike, never mind taxi-ing to Sierra or backtracking!
