And I think it's not a bad idea, forcing everyone to specify a bunch of boilerplate does not really result in people researching which machine type is good for them, people instead just copy paste from a random website. So maybe we can detect that basic usage somehow (I only have some vague ideas) and then set a bunch of defaults that we consider best? -- MST
