Well, that's for the GNOME stuff. This is a system-wide change proposal, is it not? Additionally, you could still be meeting that requirement here, as a new install with the same options selected, that is, to have a swap partition, would disable the zram device. That'd be a nice middleground for users like myself that don't have enough RAM to waste on a zram device. I'm writing this email on a Lenovo ThinkPad X200 Tablet with 6 GiB of RAM, where giving half of my RAM to zram would kill my system's performance, if not quickly cause OOM.
I think you've completely missed the technical description of how this works. It does not take more than a tiny bit of RAM when it's not being used. It definitely does not take half your RAM right away. It only starts using RAM when you would otherwise be going into swap. Then it takes those pages that would be going to disk and compresses them so they use less RAM. So no it will not kill your system's performance and will help avoid the OOM condition.
