That would be a very slippery slope and quite unsustainable. And even then I don't think a colostomy bag would automatically qualify a person even if they did do automatic qualifications for some things.
A colostomy bag is not
supposed to fail like that. They cannot give automatic
DAS for everyone who has a diagnosis or problem where something
might go wrong. Almost every person in existence would qualify at that point, as everyone can conceive of a situation that something can go wrong in a queue for them.
They simply cannot have a majority of visitors using DAS or it doesn't work. The LL line has to be short enough that those who can't wait long periods of time in line can still use it after their DAS wait. It has to be reserved for those who
will or most likely will have issues in the line every time.
