Any ROMs (or tweaks) that allow tap-to-wake?

I'm really missing the tap-to-wake from some of my previous phones and I know it's possible on the stock firmware for the S7 Edge.

There are a lot of proximity-based tap-to-wake mods but these are not the same as tap-to-wake.

Now that the snapdragon version is able to be rooted, I'm wondering if any ROMs or Xposed tweaks exist to add this feature?
