Any RIR - or LIR - that considers allocating space in sizes smaller than a /24 (for the purpose of announcing to the DFZ) would do well to read this report from RIPE Labs:

https://labs.ripe.net/Members/emileaben/has-the-routability-of-longer-than-24-prefixes-changed

tl;dr: it's still a bad idea to allocate smaller than a /24.

RIPE has long allocated up to /29. Not everybody needs addresses for the Internet; some just need a guarantee of global uniqueness.
