I agree to that, but I think this is not going to change as the outcry would be big, as people here like the minimalism. And I like minimalism, too, but I also seldom upvote on mobile, because it takes too much effort to hit the tiny spot and then "undown" again because I missed again. Custom CSS is possible though ..

It's more than possible to increase the sizes and while we're at it scale that to the size of the screen. It will take some effort but it will save the community and add to many upvotes.
