Kangie and I have already discussed this a bit but filing a bug to keep track. OpenJDK (dev-lang/openjdk, dev-lang/openjdk-bin), Go (dev-lang/go, dev-lang/go-bootstrap), Ada (sys-devel/gcc, dev-lang/ada-bootstrap) all follow the model of "main package never downloads any binaries, depends on || ( self bootstrap-pkg )". Rust currently doesn't conform to this. We have dev-lang/rust and dev-lang/rust-bin, but dev-lang/rust[-system-bootstrap] downloads its *own* binary (same as rust-bin) rather than depending on dev-lang/rust-bin as appropriate. This situation is inconsistent with other ecosystems, makes it awkward when we provide our own binaries for certain arches (because we only put them in dev-lang/rust-bin right now and have to force system-bootstrap on dev-lang/rust, despite that being misleading and confusing for Portage), and also makes it hard for users to see a binary is even being used. All of this is easier now we have proper slotted Rust.
Note that for Go, we did briefly do what Rust did, but on IRC we discussed it and consensus was to not do that: commit 7d13afbc883539b4f9fffc7d6f115b4aea591b4e Author: William Hubbs <williamh@gentoo.org> Date: Sat Feb 17 12:05:36 2024 -0600 dev-lang/go: simplify bootstrapping This changes the live ebuild to download the appropriate bootstrap tarball directly instead of using the dev-lang/go-bootstrap package.

Between the PATH manipulation that the eclass performs and the exported `RUSTC` we should see significantly more consistent bootstraps. Without this change `eselect-rust` would determine which `rustc` to run, resulting in build failures if an incorrect Rust was selected (which is nearly always in the age of slotted Rust). This is also one step towards removing USE=system-bootstrap entirely; now that we can reliably (and trivially) select appropriate slots for both dev-lang/rust and dev-lang/rust-bin we'll shortly be able to avoid downloading bootstrap bins at all.

This isn't a big change; dev-lang/rust without system-bootstrap would previously download its own bootstrap binary (same as rust-bin) instead of depending on dev-lang/rust-bin as appropriate. dev-lang/rust will now always receive an `||` dependency which ensures that an appropriate dev-lang/rust{,-bin} is available on the system to do any required bootstrapping. This will reduce Rust maintenance overhead, and make it more transparent to users that a Rust binary is required to bootstrap rust.

Did you forget to drop "system-bootstrap" from IUSE in dev-lang/rust-1.{71,74,75,77,79,80}*-r100.ebuild, or did you intentionally leave the flag in those older versions as a no-op?

wrt the Go parts, see bug 941769 too.
