Respectfully, no.
PI means provider *independent*. If I apply for PA and assign /48s, my customer is not free to multihome simply, or move providers without renumbering.
Actually you can multihome, as simple as it gets. Who can stop you to set up personal peerings with others, just because you're already in routing tables (as part of the bigger PA alloc prefix)?
Whether I submit an application for PI on behalf of my customer, or whether RIPE give them some PI because of this policy, it doesn't change my customers' ability to multihome or even terminate their service with me.
As I've said above, multihoming is possible inside of PA, but you (almost) always will get being tied with PA holder, i.e. in (almost) any case you will be visible as part of PA alloc announcement, more speficial is preferable, remember.
Once again, PA and PI doesn't really differ from routing point of view.
I think it is different from operational routing point of view: If you have PA prefix you can announce your routes only to your provider unless you have different agreement with your friendly peers. But these friendly peers should not announce your PA routes anyone else upstream. Aggregation should happen via your provider allocated PA for you. In case of PI you much more freedom....
