Right.

If you only add thouse variables you really need AND if you know the
impact they could have to the behaviour of Exim itself or its libraries
or forked subprocesses, you're save. To be even more save, you may let
keep_environment untouched (empty list) and add the variables and values
you need with add_environment.
