They may not cost more for us devs, but does it factor in the time our customers are not doing what they need to do because of that bug? I mean I fixed a trivial-to-fix bug the other day that probably Rust would have caught. Between the time it took for them to report it, support doing their thing and a new build was out it took an hour. An hour that our customer couldn't do what they needed to do for their work. So I'd say it's almost trivially true that a bug caught before release costs less to fix.
