If you do that, you need to be careful to not do

        ENV=$HOME/.bashrc

and instead do

        BASH_ENV=$HOME/.bashrc

in your .profile (or .bash_profile, or whatever).  The reason is that
modern shells honor ENV, and will happily read what ENV points to when
starting a script or subshell.  That effectively undoes what the workaround
I suggested is trying to do: don't have CDPATH in the environment for
scripts.
