Not only was it not discussed, but also it is code removal w/o core approval.
Maxime: this does not mean you are not right, but even if you should be
right, this needs prior public discussion and a guide for others what
tools to use instead. You can not just use the big axe and later come up
piece by piece with necessary details to understand the change.
To you it may be clear (at least after your "instructions" in this thread),
but others may have trouble parsing or finding it later.
