A stop sign that serves no purpose than to slow people down will piss off drivers more than anything, and lead to people speeding between signs or running them. It will make your street noisier as impatient people aggressively obey the signs.
A typical neighborhood would be much better off if traffic was calmed by adding kerb extensions or narrowing the lanes.
I think the above commenter might share my frustration that local politics is often full of people unknowingly demanding the wrong solution to their problem.
