ok so you don't care at all about the users, that's disappointing to hear only just to save 5 seconds writing the script to zip builds separately, and itch.io has API to upload releases btw, so you could save even more time if you wanted, but i doubt you want, seems you are fine with bloatware (i wouldn't mind if it was 2x 250kb like tilekit i mentioned in other comment, but here it's electron.. but that itself is an other problem, let's stick to the 2x download size issue for now)
> It shouldn’t affect anyone, except for some extra 30mb to download, which is… well, not that much imho.
selfishness
each 7zip is 50mb, so you waste 50mb shipping useless bloat
50mb for one user
let's say 100k people download your app
that's 5TB of bandwidth wasted, and it's 5TB of avoidable IO operation on people's SSDs
devs need to respect me and my PC
