I'm having grep -q read input from a pipe. I would like grep to exit

Grep used to behave almost that way. It did wait for a newline but it
did not wait for EOF. But people started complaining about that behavior
so we changed it.
Perhaps there should be an option to switch between old and new behaviors.
However, not waiting for a newline is problematic; although doable it
would be a bit of a pain to program and not sure it's worth the effort.
Grep didn't used to do that.
