In librsvg, breakages with more recent Rust versions in the past year required updates of two vendored crates: https://gitlab.gnome.org/GNOME/librsvg/-/commit/de26c4d8b192ed0224e6d38f54e429838608b902 https://gitlab.gnome.org/GNOME/librsvg/-/commit/696e4a6be2aeb00ea27945f94da066757431684d
For updating Rust in Debian stable for the next Firefox ESR update it would actually be useful if these violations of the "hard stability guarantee" in Rust get fixed, so that the old librsvg 2.44.10 builds again with the latest Rust.
It also makes me wonder how such regressions slip into Rust releases.
