Unused dependency warnings on nightly

[theemathas]

As of rust version 1.100.0-nightly (2026-09-02 2e2b193f8ada105f2760), the playground emits a lot of "unused dependency" warnings like below. It would be nice if they were suppressed.

warning: unused build dependency `addr2line`
 --> Cargo.toml:1:21
  |
1 | [build-dependencies.addr2line]
  |                     ^^^^^^^^^^
  |
  = note: `cargo::unused_dependencies` is set to `warn` by default
help: consider removing the dependency on `addr2line`
warning: unused build dependency `adler2`
 --> Cargo.toml:6:21
  |
6 | [build-dependencies.adler2]
  |                     ^^^^^^^
  |
help: consider removing the dependency on `adler2`
warning: unused build dependency `ahash`
  --> Cargo.toml:11:21
   |
11 | [build-dependencies.ahash]
   |                     ^^^^^^
   |
help: consider removing the dependency on `ahash`
warning: unused build dependency `aho_corasick`
  --> Cargo.toml:15:21
   |
15 | [build-dependencies.aho_corasick]
   |                     ^^^^^^^^^^^^^
   |
help: consider removing the dependency on `aho_corasick`

(etc)

This is probably a side effect of rust-lang/cargo#17298

[shepmaster]

Going to be reverted in #1276

It seems the warnings are still present when running Miri.

I think that one isn't my fault, at least. Once this makes it to nightly it should be fixed? rust-lang/miri@df1e16d

It seems the warnings are still present when running Miri.

That should be fixed with the next nightly.
