hehe, I would not say that I disagree. you are right, ideally the system won’t really need to swap with a huge amount of ram and nicely configured stuff, BUT especially in that case - why disable swap then, it won’t hurt in any way if it’s just there.
I did not mean to sound offensive anyway, my point was more about the statement towards providers enabling it per default or not. based on the quote I could even say now you imply a good provider must enable swap, simply because he cannot know the use case of his clients and therefore can’t expect them to buy big enough VMs or configure their stuff properly 
so it contradicts a bit to your first post ^^
