It would be a problem only if one downgraded libxrandr to a previous version. Usually distributions don't update libxrandr or the Xserver in stable releases. This means that g-d and g-p-m will have to be rebuilt (in this case) in order to be used with previous versions of libxrandr. In any case future upgrades won't be a problem.
