Yes. Look through the history of how these discussions are done. That is the way.
Having one thread with discussions of 8 seperate OS is way more chaotic and harder to parse what the community actually wants, which is why this is typically not allowed.
Here is an example from today of @fria suggesting the same thing in a different thread. New android apps suggestions - #2 by fria
This would actually benefit OP as there is basically no chance of getting community consesnus to remove all 8 desktop OS they are suggesting where there is a much higher chance if each one is considered individually.
I agree.
I also think “overchoice” is a ridiculous reason to remove something or as a reason to not add something (which I have seen previously).
