This is much better but I think it could still benefit from a little tweaking.

I suggest replacing "Justification...transition technology" with:

"Justification for the subsequent subnet size will be based on the
plan and technology provided. No organization may hold more than a /24
under this subsection."

I'm being a little pedantic here, but the language doesn't specify
transition technologies for allowing an additional allocation yet does
specify transition technologies for the limit. I think it's smart not
to limit the application to "transition technologies" but the safety
limit should apply across the board.

The text also specifies /24 as the limit per allocation. It doesn't
clearly stop folks from coming back for additional /24 allocations.

I realize this is a last call, but given the time constraints for this
policy to be helpful, I offer these suggestions here in lieu of
objecting to the major changes from draft to last call that would
ordinarily recommend returning the document to discussion for the next
