"Although the IPv6 address space is huge, it's still finite. Users only needing a /48 (or less) for their organisation would also block a full /29 prefix when forced to become LIR which seems unproportioned."
But some years ago, the RIPE NCC stated that it was using a bisection approach to allocate from its /12: https://www.ripe.net/ripe/mail/archives/address-policy-wg/2011-July/006176.h...
Is that still the case and if it is, it would be good to understand how each new /32 allocation blocks a /29.
Since the initial allocation today can be a /29 with "no questions asked", this is not so much a matter of "reserving 3 additional bits, in addition to the allocation" as of "the allocations are this size today". (Not exactly sure what happens if a LIR steps up and says "I only want a /32!!" - Marco, can you comment on that? Will the NCC still *block* the /29, or might it happen that other /32s out of that /29 will eventually be allocated to someone else?)
