I appreciate very much the way how John is trying to keep everybody aboard.
I like the idea of getting a better enclosure by modal arithmetic
I see the importance of Kaucher intervals in algebraic extensions

We are preparing a standard, which should (and will) be progressive.
As a standard P1788 has to fix or prescribe the rules for One flavor of intervals
and NOT open up new alternatives.
I completely agree with the statement that we must not build a standard with alternatives.
I completely reject this line of argument. It's like saying IEEE754 should not have the "alternatives" of binary and decimal arithmetic.
In fact the comparison seems to me to be very close. Binary and decimal are the two "flavors" of 754 arithmetic!
If you say "the interval flavor concept is premature, we haven't time to validate it", that's a valid argument (though I disagree).
If you say "90% of interval workers use set-based intervals so standardise on that", that's a valid argument too, though if you asked where 90% of dollars earned by interval algorithms came from, the answer would likely be different, as we know.
But to say a standard should not cater for alternatives simply doesn't hold water.
