Currently Backtrace support has a (documented) limitation of requiring nightly rust. Presumably, this is to use `provide` API. We'd like to use `Backtrace` and `#[from]` generation in stable rust, but it currently is tied to unstable `error_generic_member_access`. `Backtrace` is stable since rust 1.62.0 would be nice to use it without implementing From manually and use provide api only when it is available.
