I was thinking a bit about this and could not decide for long time.

I would say to save the last bits of v4 addresses for folx, that will 
actually connect end/residential users to Internet infrastructure and 
will be in need of at least some small amount of v4 in order to run 
nat64 or any other transition mechanism. That's was called PA space in 
the past.

IPv4 PI was never meant for that, but more for enterprises in order to 
be able to multihome. That luxury times are over and I think that the 
policy should reflect that.
