What makes punching holes in PA space more attractive than PI space for 
them?

This is not an idle question.  While there are many obvious technical and 
business reasons for multihomers getting PI space, I'm unable to identify 
_any_ reasons for the end site to prefer PA.

It's a perfectly balanced policy.  Filtering is to be done on RIR allocation 
boundaries, and those boundaries are currently /32 for PA and /48 for PI. 
This is no different than what is done in v4.  In fact, the whole goal was 
to make v6 multihoming the same as v4!

You're missing the point.  PIv6 is all about giving people the _ability_ to 
multihome.  Multihoming in PA space (v4 or v6) is not an option for both 
technical and business reasons.
