It's reality.

In the RIPE region, being multihomed or planning to be it is not a
sufficient condition for getting a PI prefix. And even if it was, the
hit on DFZ is the same as from getting allocation from LIR. Even if
they get their own /32, the hit would be the same (modulo individual
FIB/RIB implementations).
Consequently, there's work in progress to modernize RIPE IPv6 address polic=
y.
