My argument is that many people come to a cli utility expecting that <foo /path/to/myfile> simply works.
So are for or against that? If you're for the < /path/to/my/file argument, then we are in complete agreement. A command line application should read from stdin where that applies.
I want stdin to work. I also want specifying a file name to work. I think supporting both is good UI design, and follows the principle of least surprise.
