#![warn(clippy::redundant_feature_names)]One run
cargo clippy -- -W clippy::redundant-feature-namesThe [lints] table needs Rust 1.74 or newer. In a workspace, put it under [workspace.lints.clippy] and add [lints] workspace = true to each member.

Why is this bad?
These prefixes and suffixes have no significant meaning.
Example
[features]
default = ["use-abc", "with-def", "ghi-support"]
use-abc = [] // redundant
with-def = [] // redundant
ghi-support = [] // redundant
Use instead:
[features]
default = ["abc", "def", "ghi"]
abc = []
def = []
ghi = []
