While running `cargo-semver-checks`, there was an issue that was surfaced
regarding `serde(into)`, `serde(try_from)` and `schemars(transparent)` being
used, and they are incompatible.
This appeared to be a semver issue, on the side of `schemars`, since the issue
would only appear when adding `radicle` as a fresh dependency. The intuition for
this is that once `schemars` was updated locally, the same error appeared when
attempting to build the `radicle` crate.
To avoid this, `schemars` provides a `!` operator for the macro[^0]:
> You can also “unset” serde attributes by including them with a ! prefix in a
> schemars attribute, which will make schemars ignore the corresponding serde
> attribute item
