How about a free-moving focus point controlled by the shutterbutton?

The shutter button could have a joystick function that would allow a precise focus point to be moved at will. When not in use, the shutter button would lock in place for normal use. If it was sensitive enough, it could move the frame width with little side to side movement of the button, thereby not compromising shutter button push ergonomics. It would help preserve composition because you wouldn't have to accommodate movement of the frame to secure a desired focus point.

What's wrong with the idea of using a 4-way selector button with your thumb?
I guess to answer that question myself, it's possible that your thumb
might be occupied using another button like AF-ON for continuous focus,
but OTOH unless you'd disabled focus on half press of the shutter
button, you could use your shutter finger to focus instead.

I think you've come up with a solution to a problem which doesn't really
exist.

The Fujifilm focus point joy stick on the X-Pro2 and the X-T2 have been
well received.

The EOS-M has a touch screen trigger that focus and shoots at a tap a tad
slowly, if you ask me... "One tap shooting"(r)! I've only used that
"feature" accidentally...

My Nikon D300 and now the D750 have that exact ability.

a camera with a limited number of focus points.
