The notation using \equiv is somewhat ambigious, and few have notice that they can use \stackrel to create a =^def style notation. to ease their brain, a shortcut notation (\def) shold be made (see patch for patch)
Created attachment 2596 [details] the patch
Is this legitimate notation? Outside of Wikipedia, I've seen ":=" and "\equiv" but never "def" over "=".
It is used sometimes, though not very extensively. However, I don't think this is a good idea. Firstly, \def already has a meaning in TeX (it defines a macro), so it will be very confusing if it means something else on Wikipedia. Secondly, I generally dislike the addition of nonstandard commands. Many people who edit <math> formulas are familiar with (La)TeX and hence they won't be using any nonstandard commands and will even have trouble understanding them.
