I understand the combination of the two features is clunky and could lead to odd corner cases, but the "-x" argument is a feature I actually use on a fairly regular basis, but I am unlikely to use mca_base_env_list unless given no other choice. It's just a worse, clunkier interface unless one really needs to set that MCA parameter via environment variable.
So can we just strike the deprecation warning that is currently issued when "-x" is passed in the absence of "mca_base_env_list"?
