Because package.el does the compilation on the user's computer, not the developer's. 

It would be nice to not bother the user with warnings that are not his fault. All it would take is a global var to prevent the compilation window popping up. (maybe this exists already and I don't know). The buffer can still be created, and it can still pop-up if there's an error, but if all we have are warnings we shouldn't be throwing them at the face of a user who's just trying to install a package.
