why is this any different from the external enclosures? they have always

In the past enclosures supported only one kind of connector so this
assumption was fine. But nowadays an external disk may have several
connectors (like USB, Firewire and eSata). Why should the disk's name
depend on what type of cable did I manage to grab first? It is the
_same_ disk regardless of the cable type.
the right type for the type of cable you choose to use. yes it's the same
disk, but by choosing to hook it up in a different way you get different
results from it (different performance, different predictability)
again, if you want to have a udev rule that then maps these different name
onto the same name, more power to you, but why do you insist on makeing
_everyone_ work that way (or go to significant extra effort to find the
info in the changing directory structure of sysfs to track down the info
that you throw away)
There is one thing however that could be improved: renaming a disk in an
udev rule should propagate the new name back to the kernel, just like
renaming an ethernet interface does. That way mapping error messages to
physical disk locations could be made much easier.
definantly.
