Delay siblings from AnkiWeb on AnkiDroid

Is there any possibility that addon ‘delay siblings’ is programmed for AnkiDroid?

For me, it is pretty much the most important addon for learning vocabulary in both directions. Unfortunately, I am limited to having my laptop with me at all times, although I used to learn with my smartphone quite often.

I know there are no addons for AnkiDroid, but is there any possibility of it being natively integrated? I’ve already read on several forums that this would be very very useful for a lot of people.
