Because it basically ends up same as U-Boot environment... at least by
inheriting the commandline from the bootloader we can exercise a light
touch in this append file to only set exactly those "debug features" for
"special need" that is required, without doing stuff like making the
filesystem image itself fragile to whether it runs from NAND or SD, and
which partition, etc.
I'd like to implement these features now, but it makes sense to take
your patches first I think: when are you planning to send them?
