Is it really good goal to get rid of "-e"?

I know that the environment used in bitbake tasks is already well
defined and controlled, but I still find a bit more control with -e to
be useful in many cases.

I know I'll be able to return -e where useful, but what's the main
advantage of removing it from default?
