sticky keys without lock in macOS Sierra

In macOS el capitan I used karabiner to get sticky keys without lock feature, but after updating to macOS Sierra, karabiner does not work and it's successor karabiner elements does not have the feature of setting sticky keys without lock :(

Is there any other way of getting this to work? i really depend on sticky keys for using emacs and I find it annoying whenever I accidentally press a key modifier twice and it's locked in and i've to press it again to release the lock.

karabiner developer announced on karabiner website that macOS Sierra is not yet supported

macOS Sierra support status

Karabiner does not work on macOS Sierra at the moment.

We are developing Karabiner-Elements which provides simple key modification for macOS Sierra at first. (Karabiner-Elements works well on macOS Sierra. We are working on fixing several remaining issues.)

We'll start updating for the full featured Karabiner for Sierra after Karabiner-Elements is completed.
