Sure enough the LVM subsystem could make things better for one to not

it shouldn't need all of the PVs you just need all the pv where the
rootfs is.
is set up such that you only bring up the devices that hold the actual
root device within the VG and then you change that, say by taking a
snapshot of root, moving it around, growing it, etc, you'd be better
off if you could still boot. So you do want all of the VG members to
be around, just in case.
in this case just regenerate the initramfs after modifying the vg that
contains root. I am fairly sure that kernel upgrades are far more
frequent than the addirion of PVs to the root VG.
Yes, this is an argument against root on LVM, but there are arguments
*for* root on LVM as well, and there's no reason to not support both
behaviors equally well and let people figure out what works best for
them.
No, this is just an argument against misusing root on lvm.
