Strunk & White has been criticized by linguists. The reasons (at a very high level) are that it is prescriptivist (and some style manuals in the US such as the Chicago Manual of Style have become quite liberal (meaning more descriptivist) recently) and linguists have demonstrated that it is incorrect/inconsistent and outdated in a number of points; see here for an intro to and pointers for the relevant debate.
This is not to say that Strunk & White isn't without its merits and valid points and achievements and that it hasn't become an important part of US-American copyediting history. Also, many people still hold Strunk & White in high regard.
With this in mind, would it be possible to rename this badge? To me personally, this badge feels a bit like a prize awarded that carries the name of (say) a famous politician that has fallen into disrepute ;-)
(Also, the badge sounds US-centric, both because of the name itself and because the prescriptions in Strunk & White are not necessarily well-known or obeyed in other English-speaking countries. I understand that this might not be regarded as an issue by some, but I would still like to mention this fact, to provide more information for a discussion.)
What about "Assistant Editor"? Just one idea; there might be many other suitable names.
