I think all my emails on this subject have been seriously misunderstood.
Perhaps the problem is that I don't understand some critical issue.  Can
you please help me understand this part:

It seems like people want releases, starting with 10.0, to be named things
like 10.0, 10.1, 10.2,..., but for the purposes of communicating with programs
like nagios refer to them as 10.0.0, 10.0.1, 10.0.2

Is that right?

That's the part that really annoys me, and I keep trying to argue for not doing
that, and people keep replying to other parts of my messages rather than
replying to the core part of what I am saying.

Why would any sensible person want a release to sometimes be called
"10.4", but the exact same release sometimes referred to as "10.0.4"?
This is just going to confuse average software users, as they would never
expect that 10.4 and 10.0.4 are the same thing.

Have I misunderstood what is being proposed?

The only reason I talk about using the middle number for this other purpose
is to forestall people assuming that they can elide the middle number of a
three number system, such that it gets elided sometimes but not other times.
I was quite clear in my email this morning that I'm not arguing for a three
number system.  I'm perfectly ok with a two number system.  I just don't want
a "let's confuse everybody by making each and every release have two
different names" system.
