After reading the sources, AFAIK it's sufficient to load it when
compiling.

You can use the `gv-setter' declare spec in your defun.  Then the byte
compiler will autoload gv and put something like

  (put 'function 'gv-expander [byte code])

in the compiled file.  That doesn't depend on gv when loading.

OTOH when compiling, `setf' forms are expanded to something that doesn't
depend on gv either.

That's just how I think it works, but that stuff is used widely in the
sources.
