If you don't consider opportunity cost, there's really no reason not to have it as an option. At worst, you could get so-called "pro" players insisting on it because it's "more skilled" (kind of like how the Starcraft 2 pros resist making more skills autocast because it makes the keybinds, macros, and APM that separates them from the common herd less important), but if the option is chosen at the start of the map for everyone and can't be changed, people who don't want that can just play their own games without it.
Opportunity cost, however, is a consideration. For Triumph to implement this would require Triumph to spend time implementing it that they could have spent working on something else. Based on the ratio of "agree" versus "respectfully disagree" on the OP, this is something that only about 10% of people looking at this thread and taking the step of "voting" through the agree/disagree system want... and this is something technical enough that the people who don't visit the forums (let alone this specific thread) are probably even less likely to care about. Odds are, there is something else that Triumph could do with their development time that's going to interest more than 10% of the player base.
