Why doesn't this work? Isn't not(bootstrap) supposed to specifically address this case?

&Span is used incredibly frequently, so fixing it takes a while. As long as rustc_pass_by_value is ignored in the bootstrap compiler, it isn't as nice to deal with that.
It means that the lint will only trigger when compiling the stage 2 compiler, which most people don't tend to do before submitting their PR, causing CI to break. So it would work, but would imo be too annoying to be worth it.

Could you say in the comment that not all uses of Span are fixed, and it's tedious to fix them until it can be done at stage 0-1 when stage 0-1 supports #[rustc_pass_by_value]?
Right now it's entirely unclear from the comment why the attribute is commented out.
