1GB is not an extreme amount of memory at all, unless we are talking about vram (and even there, any gpu worth it's salt would have at least 2GB). Many games require 4 or even 8gb, and even barebones laptops come with at least 4gb and often 8gb. It's really only relevant if designing a game for mobile.
Ultimately though, not the point. It's a good warning to have as default...but we should be able to disable it.
