IMO, the test for ~/.profile should be removed.

IMO, setup should be modified to put the test for ~/.bashrc in ~/.bash_profile.

I agree.  Caution has to be taken.  'Course, caution always has to be taken.

I just tested this.  Bash reads both ~/.profile and ~/.bash_profile or
~/.bash_login.  If both ~/.bash_profile and ~/.bash_login are present then only
~/.bash_profile is executed.
