Pretend I'm channeling the 100's of people who've read the specs, and
implemented broken NASes.

No. If there *is* only one AVP in a single attribute, then that

I am, of course, not claiming experience with multiple implementations
of the extended attributes. Pretending I'm making that claim is
disingenuous at best. Instead, I'm claiming something much more
difficult to understand.
The "experience" is with previous standards, and the people who've
implemented RADIUS software based on them. It's called "learning from
experience", and "applying that experience to new situations".
I've spent a lot of time talking with implementors of NASes and
servers about their software. There are a number of styles of
misunderstanding that they have about existing specifications. That
experience can be used to review new standards, to minimize the
potential for similar problems.

Inefficient packing should be discouraged. On top of that, the size
limitation of RADIUS packets means that inefficient packing of
attributes can cause packets to fill quickly. This means that the
packets can carry less information than they would otherwise have been
able to carry.
This has implications for all networks that depend on implementations
of the standard.
