On the one hand I'm not at all convinced this bug is rc, on the other hand I don't think shipping a four year old version of env-logger in the next release of Debian is a great idea.
So I decided to look at the reverse dependencies, I found three safe-vdash - this is a Jonas package, the dependency on rust-env-logger-0.7 seems bogus, I filed a bug. rust-tracing-log - the new version no longer depends on env-logger, I updated it along with it's reverse dependency tracing-subscriber. rspotify - this package is long term broken, noctis expressed an interest in fixing it back in January but I don't know what if-any progress he has made since then.
