Bug description

It should be possible to use modified versions of modules with a custom build.
Use case: I would like to provide a modified version of the cover flow implementation (see #8113). This currently fails to build since getRotateFix is not exported by swiper-effect-utils.mjs (that seems to be the "natural" location to me) or any other of the exports. An alternative would be, to export shared/utils.mjs in package.json.

Expected Behavior
