The big problem is that the difference in sevaros may make a particular
pruzbul text valid or not.

For example, how does hefqer BD hefqer work today, when courts do
not have a central Sanhedrin organizing them? I am giving the loan
to three hedyotos. Which 3? The three I named? (Are we invoking Beis
Shammai's notion that one can be mafqir only to a given person or set
of people? [Ymi Pei'ah 6:1 19b]) Then how is it HBDH and not a simple
matanah?

GCT!
