These towers are important for stopping raiders, as they can protect sewers, RDM, GC, and cliffs all at once.
To my knowledge, the reason these two towers aren't currently a valid patrol location is to prevent AEGIS from RK'ing and SK'ing innocent wastelanders. However, I would generally expect them to follow rules and FA/SC would also be present to enforce it
Plus, wastelanders are less likely to be innocent when near these towers(they become raiders when holding a gun beyond the no gun sign or climbing the tower), unlike other locations where wastelanders need to be given a 5 second warning and can still mine the area(unless they're actually capturing)
Sure, it might be a short patrol and they'll die pretty quickly, but that's the whole point of patrols, which is to fight raiders. Also, SC might be more willing to watch a TLS/TOT patrol since it'll be shorter
