I'm not sure for whose benefit you're explaining this, I've had dual
stack networks in operation since 2001 and I'm feeling the same ipv4
addressing pressure that you are. the fact that there will be no flag
day should be obvious to everyone on this list.

No, this draft is taking a /8 from the free pool and assigning it for
private use. A private use address pool already exists. and is by your
assertion not sufficient for the purpose.

you are in fact not requesting that it be shared by operators, you are
assigning it to the pool of private use addresses. and you are hoping
that through some form of magic it will be less impactful that reusing
the existing private use addresses.

then you draft should propose a mechanism by which operators can be
assigned use of the prefix because as it stands right now it's simply
assigned under the private use definition, which means the rest of us
are going to use it immediately.
We can even use 'polluted'

Have you looked in your routing table? 1/8 is being assigned. so you're
a little late to the party on that. Any prefix assigned to an rir from
the IANA free pool will be used, no matter how "polluted" it might be.
just a small sampling...
