The `--target host-tuple` feature being stabilized is also a nice quality-of-life change.
Since I do not have a test harness for some platforms (like aarch64-unknown-uefi or thumbv7em-none-eabihf), I typically compile unit tests against my host platform and run them there. Previously, one would have to write the host tuple explicitly, like so.
The `target` value needs to be substituted for each target if you e.g. orchestrate builds with Nix or other tooling.
