v10 question: interpolation with new frame loop?

[Pinpickle]

The new useFrame API looks great! I really like the explicit FPS.

Currently, we have our own physics clock implementation which has a fixed timestep. One key component of it is interpolation. That is, if we're running at 24 FPS, but the game is rendering at a higher frame rate, the render frame interpolates between physics frames.

Is this something that the new API will support? I couldn't find anything explicit in the docs about it.

Proof of concept:

const state = useRef({
  x: 0,
  prevX: 0,
});

useFrame(() => {
  state.prevX = x;
  state.x += 0.01;
}, { fps: 24 });

useFrame(() => {
  const alpha = // a number between 0 and 1 dictating how much we are between the most recent physics frame and the upcoming one. Where to get this number from?
  const renderedX = state.prevX + (state.x - state.prevX) * alpha;
  renderSomething(renderedX);
});

Just checking to see if this a supported use-case, or something that's being considered with the new scheduler.
