Given that the currently handed-out IPv6 addresses are provider 
aggregateable addresses (=PA), and that people are now working on having 
provider-independent addresses (=PI), the distinction makes very much sense.

Of course the PA/PI distinction doesn't make sense at the layer where
the RIR is handing them out - at that layer, it's just "chunks of addresses".

At the end-user layer, there is an important difference - a block tagged
"PA" can not and must not be moved to a different provider except the
one where it was received from, while a block tagged "PI" can.

Calling it "PI" or calling it "we open the policy so everybody can get
their own independent address block" is technically pretty much the same.

The tagging just makes it very clear to end-sites receiving PA blocks that 
there *is* a difference regarding portability.
