No, they would not. They might ask to have their pseudo-TLDs added to the PSL but there's a process for that and it is definitely not our problem. >Now, we can relax our ambition to be PSL-free and state N=max number of labels >of public suffixes used by mail.

That is a great deal of complication for no benefit whatever. I'm with Scott, pick a number, 5, 8, whatever, and be done with it.
