The "anonymous function wrapper" ensures that the script's

anonymous function, so they can't "leak out" into the page, or vice
versa — the script's identifiers are all local to the script.
And so forth...
I thought I could find where it is documented that this is an archaic
way of writing GM scripts, but I can't find it now.
I wonder if someone can explain to us: does GM automatically wrap user
scripts in an anonymous function (or the equivalent) to gain the
security and scoping benefits I named above? Is it overkill to add the
anon function in your own user scripts?
