Spoilers won't improve page load. It still has to load all the resources that are being hidden. It might load a little faster because it doesn't need to render them initially but the difference wouldn't be significant.
And I am most certainly saying never. For the most part, we are zipping images and MP3s. Neither of these are compressible so we don't really care about compression ratios. The zips are here to make it possible to submit a collection of files and, as such, we really only care about compatibility. All OSes support zip archives out of the box which is why we will never accept any other format for archives.
