Quite a number of boards use an embedded environment which gets
auto-installed when programming the U-Boot image. And a significant
percentage of boards I know use some installation tool that will set
up things like serial number, MAC addresses etc. one way or another,
andin many cases this includes running "saveenv".

No, and I strongly discourage it. It just makes detection of certain
types of problems / hardware errors etc. more difficult or even
impossible.

I think I would oppose such a change because I consider it really
dangerous.
