I think that's a great start. I mean for me, I'm realistic - if it's a pre-first round or first round exit so to speak, I don't expect anything substantive, a canned response is acceptable. I get that it's a pain when you have hundreds of applicants, but it should also be trivial.

It is nice to expect something a bit more involved if it's a final round thing, but still. No-one likes the ghost.
