Is there a time frame on fixing the leaver problem?

Hello first time posting on the forums here

I noticed a while ago we got the usual message from blizzard saying they are going to implement a system where you will be put back to the front of the queue when someone leaves a game in the first few seconds (seems like something you should have done day one)

But to be frank overwatch has a history of taking far too long to fix anything. buffs and nerfs are generally too slow, new champions are maps are few and far between and its little wonder the pros are all planning to leave for other titles.

i know the standard excuse is making sure its polished but i just dont buy it after so long with so little in the way of updates. Is there an actual date this will be fixed?

I think they might implement it half-way through season 21. I remember Jeff said something about a shorter season 21.
