<p>I have just came across the ingeniously enforced "small, single-character edits should be avoided" policy. I was trying to change a "$-$" in a formula into a "$+$". I succeeded after a prolonged fight with the "at least 6 characters" script.</p>

<p>This is a math site, people. A single "$-$", or a "$2$", or a "$1/\pi$" is frequently crucial. How do we go about removing this silly restriction on truth?</p>
