Well, don't take a -1 as a formal "no", it's an opinion based on

I think what you need to do is make a test bench that proves the case.
Perhaps an EC2 instance with low virtual memory, or somesuch.
Something people can play with.
Then we can see before/after behaviour and it stops being a matter of
