Do you suppose we can convince GNU grep's maintainer to follow this
philosphy?

$ mkdir d
$ touch d/foo
$ grep foo *
$

It opens and reads, gets EISDIR, and intentionally skips printing it. Grr.

But wait, there's a -d option with 3 alternatives for what to do with
directories! ...and none of choices is "just print the EISDIR so I'll know
if I accidentally grepped a directory".
