There isn't a PHP event loop, so fibers are basically useless in
Drupal, unless Drupal is going to provide their own or use Revolt, or
something. In that case, you pretty much have to change your entire
programming model to work with it and accept the interrupts. It's
funny because fibers were intended to prevent the 'what color is your
function' problem, but instead it became the 'I have no idea what
color my function is' problem. So, just like with async/await, you
have to go all-in or none-at-all, or very carefully craft your stack
to handle multiple layers of fibers. Or maybe I've just been "doing it
wrong" which is certainly possible.
