Without serde(bound = ""), serde_derive infers a bound of `T: Serialize`
for the generated Serialize impl and `T: Deserialize<'de> + Default` for
the Deserialize impl. `X` implements none of these so the generated code
would fail to compile.

Clippy's suggested fix is not valid in 2018 edition. The
serde_test_suite crate can't be updated to 2021 edition yet because CI
of the serde crate on old toolchains needs to be able to parse all
manifests in the workspace, even if serde_test_suite is not being
compiled in those builds.
