The distinction to me is that PA space is provider owned space assigned to 
a customer.

PI space is "your space", whether assigned by ARIN or "legacy" space 
handed out by Internic or whoever was handing out space at the given 
pre-RIR time.  It's yours to use with whatever provider you want.

PA space generally can't be taken with you if you leave the 
provider...though it's not unusual to be given some amount of time to 
renumber.

IME, it would be unusual, even for pre-RIR space, for a provider to assign 
space to a customer and not expect to reclaim that space when the customer 
terminates service.  At the same time, it wouldn't be unusual, 
particularly for very large or very people/clue deficient providers to 
just never bother reclaiming space.  In such a case, I'd say it still is 
their space...they just haven't done the housekeeping to realize that the 
space should be back in their pool of assignable blocks.
