The latest thing that was said from Riot Tantram in this regards (and I'm power phrasing here cos I can't find the thread) were as follows (this was within the last 3-6 months):
Permabans is our way of telling someone they aren't welcome in our game, not to make it easier for them to come back.
and
There is a diminishing return upon every punishment tier we work on, it is more beneficial for us to spend our resources where we can get a better impact.
Meaning they rather spend time creating features that can benefit 100% of the population, instead of a feature that may / may not work for 0.006% of the population.
So that also means: no new programs for the small minor population, probably new features coming for the majority of us.
Even if they had new features for 100% of the population, they aren't sharing any details with us and have been super quiet about it. They'll tease us here and there with some smiley emojis when we are suggesting things, but that's all they are telling us.
