No. you can always reject de-aggregated prefixes based on LIR
allocations with filters. That's entirely up to yourself. Any sane
network person will send both the allocated full prefix on top of the
de-aggregated prefixes.

The choice of table-size is yours. Don't prohibit others from diversity
and redundancy.
