Could you explain this?

If query building is separate from matching, then you'll be able to match against inputs other than a flat string.

Specifically, only supporting flat strings prevents it from being extended to support "is:unread" or "title:foo"

I'm not saying you should implement those features. I'm saying it would be great if the designed allowed someone to do so.
