Hi,

Thanks for providing some context about those changes.

I'm not questioning whether those changes are valid or not. The question
is not whether they improve performance on EC2 (I'm quite sure they do),
or what other distros are doing.
My problem is that we call "official Debian" something that isn't "pure
Debian", but rather "Debian with many optimizations decided by the Debian
Cloud team".

Note that an easy way to solve this problem and have the best of both
worlds would be to provide two sets of images ("as pure Debian as
possible" vs "Debian with the Cloud team optimizations"). Have you
(team) thought about doing that?
