debcargo always uses the same clap version as cargo (since it uses cargo as lib crate, and obviously we want to avoid a duplicate version in the dep tree). it seems 0.67 (to be released in two days together with rustc 1.66, on 2022-12-15) will upgrade to 0.4, so if we want to get that in we'd need clap 4.x packaged anyhow, but if we want to stay at 0.63 (current bookworm/sid version) or 0.66 (current upstream release, I've prepared an update together with noctis, but not pushed it yet) we likely want clap 3.x with derive support in bookworm..
