That would certainly be welcome, but there are no contractual or policy
requirements that could *force* the LIR to return the space (or would allow
the RIPE NCC to take it back).
Allocation policy has always been geared to "here's a block, you fill it,
then you come back and ask for the next block" - the situation "here's a
block, and if you do *not* fill it, give back the unused part in <x> years
time" just did not happen during the growth years of the IPv4 Internet,
so the policy does not have any clauses for it.
Changing the policy to apply to old blocks would be retroactively applying
policy to *holders*, which is generally a no-go area (and I disagree with
some members of the community here on what is "retroactive" - I think that
affecting future(!) *actions* regarding a block is ok, but changing the
de-facto *status* of something people rely on is highly problematic)
