`[[maybe_unused]]` is helpful for suppressing warnings about declarations that may or may not be referenced. However, clang currently accepts it only in c++17 (or c23 for C) and later. Users who target older standards often rely on inconvenient workarounds, such as wrapping code in `#pragma clang diagnostic push/pop` to silence warnings.
It would be useful if clang accepted a spelling like `__attribute__((maybe_unused))` for earlier language modes.
