[Richard] What’s the point of a BCOP if we shouldn’t pay much attention to it?  Is the BCOP wrong, or is the allocation policy too rigid?

It's just one generalized BCOP of a design that certainly not fit into every ones network design or even use terminology that you even have anymore in your network.
Your company could receive a /96 and give every single customer device their own IPv6-address without any concerns of future IP shortage.
Your company could also receive a /16 and do the same. I would do whatever is best for you.



[Gert] ..do the math..

Generally speaking I would say it's too early to do the math due to unknown factors.


[Gert] All these arguments have been brought forward hundreds and thousands of times in the last 20 years...

20 years ago RIPE allocated /35. Then they changed to /32. Then they changed to /29. Today people need /19.  Tomorrow they need /16. The day after an /8.
However, one could argue that you could actually do the math on this one using linear interpolation and calculate day zero...
Nothing ever lasts anyway, so it's probably just fine.


have I enabled NATv6 on something today..?
- yes I have

Just do the math, please.

All these arguments have been brought forward hundreds and thousands of
times in the last 20 years, by people who were just too lazy to run the
numbers.

I am willing to reconsider my position if we hit 50% utilization of FP001
in my lifetime (*and* buy everyone a beer who comes and says "told you
so!"). In this very unlikely event (MATH!), we have burned through
half of 1/8 of the overall address space, and have 14 more tries to
make a more restrictive policy.
