AFAIK there is an existing policy/process that the RIPE NCC will create ROA AS0 records for prefixes not currently allocated to any LIR. This prevents unused IP space from being originated into the DFZ.
that was policy proposal 2019-08, which was withdrawn by the authors, i.e. never became RIPE policy. There was lively discussion about this in 2019-2020. If this was something you were interested in looking at, it would be worth looking back over the archives to understand the calculus involved, which from what I make of it, hasn't significantly changed.
