I don't think the policy is that clear-cut.

   5.3. LIR-to-ISP allocation

   There is no specific policy for an organisation (LIR) to allocate
   address space to subordinate ISPs. Each LIR organisation may develop
   its own policy for subordinate ISPs to encourage optimum utilisation
   of the total address block allocated to the LIR. However, all /48
   assignments to End Sites are required to be registered either by
   the LIR or its subordinate ISPs in such a way that the RIR/NIR can
   properly evaluate the HD-Ratio when a subsequent allocation becomes
   necessary.

   http://www.ripe.net/ripe/docs/ripe-412.html#lir_to_isp

This text seems to state that an LIR can decide how much is  
appropriate to sub-allocate to a downstream ISP. As such, an LIR with  
more than a /32 could decide to sub-allocate a /32 if they though that  
doing so would "encourage optimum utilisation of the total address  
block allocated to the LIR".
Ultimately, it's the LIR's problem if they are convinced to sub- 
allocate a /32 and the downstream ISP makes very light use of the  
space. A prudent LIR would make sure the contract with their  
downstream was sufficiently rigourous in this area.
