In answer to your direct question: No, Microsoft has not added any ability to change the color of strikethrough font formatting. I doubt that they will but if this is something important to you that using Track Changes does not solve, you should send in feedback.
Microsoft is not hearing about your problems from what you post here. You are discussing a problem with your fellow users here. We can give good advice about how to work with Word as it is and give suggestions for making it work properly.
