Obviously, you're pointing out that the technology exist ... that it is
not that hard to do. Certainly they could make TV's with a 2:1 range
of scanning both vertical and horizontal, which would be enough to lock
the CRT into an integer multiple of the timing of the source, making
conversion a rather simple task.

And this is something that can be accomplished.

A CRT display can easily do 40 Hz to 80 Hz on vertical. That has everything
covered well. 24 fps stuff can run at 48 or 72, but I'd prefer 72. My
computer display is running at 1152x864 at 67 Hz right now and it's an old
Sony Multiscan200sx.

But technology _can_ allow the producer to shoot at just about any speed
they want to. Go for what feels right for the material content.
