Thanks @eddyb. This likely won’t pass CI since rust-lang/rust#45225 is not yet in a rustc version we use. I’ll take over to make it conditional or something once rust-lang/rust#45225 lands. (Servo and Firefox use different versions.)

In the meantime, as I said in rust-lang/rust#45225, feel free to disable Stylo tests in Rust CI.

I think so. That is, we’ll get the shrinkage benefit without changing the type definitions. I’ll double check tomorrow when Rust Nightly has this change, and remove the FIXME comment.
