If a kernel is upgraded without building the necessary initrd image, that kernel will be unbootable. Newer distributions support lvm in their mkinitrd scripts as well as their packaged initrd images, so this becomes less of an issue over time. Because RedHat and Fedora build the initrd image for you, this is not an issue unless you are building your own kernel. Then again, if you are building your own kernel, you are probably an advanced user - at least to the point of knowing that you need to build a matching initrd image to take care of mounting the LVM root partition. The way I read the warning is that if your distribution does not automatically take of building an initrd image that supports the root directory on LVM, then you had better know what you are doing if you decide you want to do it. If your distribution takes care of it, then it is not an issue unless you are building a custom kernel, and in that case you had better know what you are doing.
