Would be nice, but alas, it seems we're doomed to repeat most past
mistakes.

If I understand what you're suggesting, this is the rationale for the
RIR's receiving /12s from the IANA. The theory was that the RIRs
needed /12s in order for them to allocate address space via a
bisection methodology, which would allow for growth in any of the
allocations made.
However, last I checked (which was a while ago), only APNIC had
actually carried through on this -- all the other RIRs (if they were
allocating out of the /12 blocks at all), were still allocating
sequentially.
Things might have changed (haven't been following what the RIRs do so
closely anymore)...
