With LVM on AIX, the boot "device" isn't even mounted at run time. If you do anything with the root LVM configuration, you have to update the system boot blocks, but otherwise you'd never know that the boot device even exists. In the case of an extended vinum, would it even be necessary for the boot device to be mounted after the system is running? As for the various commercial LVMs, I've used LVM under both HPUX and AIX. In my opinion, AIX's implementation is far superior. The ability to increase the size of a mounted filesystem is extremely powerful. AIX's LVM also seems more robust than HPUX's.
