So why dont they give more than one such /64 to one end user?

??

> An operator get's a *minimum* of a /32,

I can agree to that.  But I am also familiar with the common practice to
use chunks of GUAs on the interconnection links (instead of LLs or
ULAs).  There too people say "we have enough of these IPv6 prefixes, no
worry".

But it's again speculation.

> and in RIPE land can get a /29 by just asking for it.

That looks simple.

> A /40 is less than 1/2048th of a small operator's address space.

Look, let us talk only about the cellular parts of a certain country of
what such an operator may get.  I can agree with you that an operator
may get much from RIPE, but I ask how much of it will she assign to its
end users on cellular links?

Do you know of a cellular operator assigning a shorter-than-/47 prefix
to cover its cellular end users?  I am not asking to name it, but
whether such thing exists is sufficient for me.
