Not entirely.

Without policy (globally coordinated policy), I'm not sure IANA has a
way to accept and/or re-issue space returned by RIRs, at least not
in chunks smaller than /8.

That's the big question.  I, for one, feel that it is inappropriate  
for an RIR to
return space to IANA if there is a justified need for that space to be  
issued
to other organizations within the RIR's region.  However, I do feel that
it is good for excess space in any region to be returned to IANA to be
redistributed to other regions.

Well... Said RIR can, essentially opt-out of returning the space to  
IANA,
but, the rest of the policy would still stand.  However, with a simple
policy change, an RIR can make it impossible to return space to the
RIR, so, I'm not sure there's much of a difference there.

I think it is reasonable to make enabling policy without necessarily
making it a forced issue. RIRs certainly should be able to return excess
space to IANA and certainly should be encouraged to do so. However,
I have an issue with RIRs being forced to return space which may not
be excess within their region, so much as in need of redistribution
within the region.
