Component AsRef change causes beta regression

[Mark-Simulacrum]

This is probably going to be closed as expected breakage. This means those cc-ed below should probably aim to fix their crate and release a new point release.

#46985 added an impl of AsRef<Path> for Component which causes these crates to stop compiling:

• artifact-app 1.1.0-beta001 app_dirs crate no longer builds on nightly #47466 cc @vitiral
• app_dirs 1.1.1 (Type of this value must be known in this context on 1.25.0-nightly andybarron/app-dirs-rs#28) artifact-app fails to "cargo install" with nightly #47480 cc @andybarron
• gutenberg 0.0.7 log cc @Keats
• rst_app 0.3.7 cc @vitiral
• second_law 0.2.2 and 0.3.1 cc @nathanross
• tack-it-on 1.0.1 cc @ChrisWellsWood
• tango 0.6.2 and 0.8.1 cc @pnkfelix
• yabs 0.2.1 cc @0X1A
• Redrield/kobalt-updater @ 6cd602b7ccf16336c8acc1c4d808b37152c648f7 cc @Redrield
• vitiral/artifact @ ed4d744c67d8a7ed41c202b0ac81e2ae2720b3fb cc @vitiral

Estimated ecosystem breakage: 143 versions (0.18% of versions published), 39 crates (0.27% of crates).

Unfortunately app_dirs is no longer maintained, with no good replacement that I can find.

[vitiral]

For crates that are no longer maintained what is the right course of action here? For instance rst_app is just the previous name of artifact_app so I have no intention of fixing it. Should I yank it?

[carols10cents]

@vitiral You could put maintenance = { status = "deprecated" } in the Cargo.toml of rst_app, and possibly mention that it was renamed to artifact_app in rst_app's description.

This was discussed during the libs triage meeting recently and we decided that we're not going to revert this, but if any crates need assistance updating we're more than happy to help!

Closing due to previous comment

For anyone looking for a replacement for app_dirs, try app_dirs2 or directories.

#46985 is in relnotes, but this issue wasn't mentioned at all despite of the compatibility breakage (not to mention promised compatability guaranties).
