(Get the code!)
I'm open to raising the default for future releases if it is no longer reasonable. I'd say if a 512M LXD VM can not crash dump w/ 192M, we should bump it. If 512M VMs still work w/ 192M, but 1G needs more, let's bump it for the 1G: range.
However, I'm not convinced this is something we should SRU, unless you can somehow demonstrate that the default works for no one. We are literally stealing memory away from the OS here, and rebooting a VM after applying updates to find your application now OOMs would be a clear regression.
