Frankly, I use 1 for about 99% of my shots. For the other 1%, I

That is because your subject rarely moves.

9 is a nice number because you have direct access to each of them
with a single click of the joystick.

9 is good. Some cameras come with fewer, especially the entry level models.

What I'd like is for all of them to be as good as the center one.

So, you want more than 1? LOL.

In fact, I'd like the 8 peripheral points to be the same as the
current center point, and the current center point to add reliable f8
focusing capability. This would be great for using 1.4x TCs on the
f5.6 lenses like the 100-400L and 400/5.6L.

But for what reason would you want more points? Tracking an object
works just fine with 9. In fact, it works just fine with 1 for me.

There are holes in the coverage with just 9. Some elusive subjects sometimes will not come into focus because none of the 9 can find a target with sufficient contrast. Having more focus points increases the odds of getting the shot. I suppose manufacturers like to charge more if their camera are more likely to get the shot. As consumers, it is up to us to decide whether that capability is worth the money being demanded from us.
