You're saying you have solid technical reasons, but they are so
self-evident that you can't even begin to argue them. Why are you so
sure your reasons are solid?? Regrettably, I say this doesn't make any
sense, however much you write.

The decision may already have been made in your eyes, but the community
still has options as to how to proceed, whether or not Masao has already
written this.

Zoltan has already presented a patch that follows my proposal, so there
are alternate valid paths which we can decide between. It's not a matter
of opinion as to which is easier to code cos its already done; you can
run the patch and see. (No comment on other parts of that patch).

The alternative is an approach that hasn't even been presented itself
fully on list, with many unanswered questions. I've thought about this
myself and discussed my reasons on list for the past two years. If you
can read all I've presented to the community and come up with a better
way, great, we'll all be happy.
