I'm not proposing a policy, I'm proposing text for a "Recommended
Practices" document.  If we want to eliminate the "distinction" between a
transit-buying and transit-free transit provider (which IMO is a valid
technical distinction, egos, tier labels, and salesmen aside), then you
simply need to expand the recommendation to say something like this:

To multihome with PA space, you must ensure that your transit providers,
and any of their transit providers (recursive), accept your /48 from each

Still pretty simple, no?
