I would be curious to know which things you're referencing. Because I'm looking at it right now and it mostly seems fine. No icons or anything seem overly large.
Try and squeeze discord into a 400x400 window (or something similarly small and out of the way) to put in the corner of your screen. Mission impossible.
Squeeze an IRC client into 400x400, and you'll still have plenty of room to read what's going on.
IRC sample (it's not 400x400, but you should get the idea):
I think there's a lot that could be done to make Discord more desktop real estate friendly. It's one semi-dealbreaker for me too. I can't have one single chat app require almost one whole new monitor.
