We might have to remove i686 as an available architecture option; i686-apple-darwin is listed as a Tier 3 platform on the rust-lang.org website(1), defined as follows:

Tier 3 platforms are those which the Rust codebase has support for, but which are not built or tested automatically, and may not work. Official builds are not available.

Replying to herbygillot:

That's probably fine. Cargo's dependency rust already requires a recent OS to compile and thus is not compatible with 32-bit-only systems anymore. And since cargo is just a dependency manager and doesn't install libraries, its non-universalness shouldn't prevent other ports from being universal.

OK, PR is here: ​https://github.com/macports/macports-ports/pull/6700

cargo-bootstrap no longer exists, so I think it is safe to close this ticket.
