Just be aware that the number of years is likely to be quite small.
According to the statistics published on the RIPE NCC's FTP site, it
assigned more than 1,000 /24 prefixes last year.

The same statistics indicate that about 3,700 prefixes of all lengths were
assigned or allocated last year. I don't think we can assume that demand for
IPv4 address space will reduce and I also think it is reasonable for
networks that would previously been happy with some PA space from their ISP
to get space direct from the RIPE NCC if it is the only game in town.

I don't know how many years people want small blocks of IPv4 address space
to be available for under a policy along these lines but I think if it is
more than just one or two it probably needs to be designed in a way that
takes account of historic demand and how people will react when other
avenues are cut off.
