Maybe everything would be a lot smoother in the future if we started

Maybe even
lurk in a "short UUID" there (ext3 fs labels are limited to 32 bytes
IIRC): for example "F7-1234abcd-/".
Anyway; right now it's some what a mess having more than one Fedora
install on your drives and, from my personal experience, this have
discouraged me from doing such things.
You might also hit this situation if you have Xen / KVM guests using
parititions in the host as their virtual disks, if they don't use a
nested partition table inside the guest. eg, you end up with something
crazy like /dev/sda1 is labeled '/' for the host, but you setup a
guest with /dev/sdd1 as its root, which also ends up labeled '/' by
default. To avoid this we recommend people partition /dev/sdd1 inside
the guest & have anaconda do this by default, but including a short UUID
would address that problem more generally.
Similarly there is fun & games with logical volume names - both host and
guest use VolGroup00 by default. So if you want to access data from a guest
partition in the host its very easy to get totally & utterly confused.
