"discourage" != "cannot"

Absolutely! I also think that a large confusion comes from wording: I
assist Charlie and Stan that you _are NOT prohibited_ to continue
using your setting with LLs. Nowhere in the draft this is prohibited.
Nevertheless, I hope that the revised section by Charlie can help to
make that clearer. Are there any other opinions on that revised
section?

Ulrich, call this draft "discourage!=cannot" and you'll have many eyebrows raised...

No one supporting the Bacelli-Townsley draft has said you can't use
link-local addresses. I support the Bacelli-Townsley draft, and most of my
deployments use link-local addresses. My deployments will continue to use
link-local addresses. But I do see that there are deployments where use of
link-local addresses is either problematic, or impossible. So I understand
the draft's language concerning "discouraging" their use.

But the draft DOES NOT say they CANNOT be used. That's one of the reasons I
support the draft.

Stan

Hello Alex,

I don't mind discussing with you.  But I really don't
like having to point out your false statements so
often.

So far the only hard problem seems to be how to avoid squabbling over
 whether link-locals are needed.

I am not sure why the proponents of necessity are so adept at
ignoring the solutions that do not need link-locals.
It's very simple why: I have a prototype which involves protocol
extensions (RA) only on the parts of the System which use exclusively
link-locals addresses.  You forbidding link-local addresses equates with
forbidding my protocol extensions on the core of my prototype, makes
all break.
I _do not_ forbid link-local addresses.  I'm not even one of the
document authors, and I didn't create that language.

But the document does not forbid link-locals either.

So how many times do you persist in making this false
statement, and, worse, basing your repeated, iterated,
verbose, relentless, and seemingly misguided objections
based on the false notion that link-locals are forbidden?


It is not explainable by the existence of solutions that use
link-locals, because such solutions are universally acknowledged to
be useful in their realm of applicability.
Is this formulation ok, or an "only" missing somewhere?
...???...

If you keep that formulation as is - I agree with it!

So why do link-locals insist on "their way come hell or high water"?
BEcause I don't want my prototype discarded by an illogical sense of
forbidding LLs.
And in what universe does that prohibition reside?

Regards,
Charlie P.
