I find the new behavior more useful, too.

Before its addition, I would sometimes type "grep -r PATTERN", and it
would take a few seconds for me to realize the lack of output was not due
to a big directory with no matches, but due to that old grep waiting for
something on standard input.  That was frustrating, so I do appreciate
the new behavior and would like to retain it.
