    Legacy semconv keys (http.* and db.*) are sourced from the `_incubating`
    attribute modules, which still define these exact string values.
    `opentelemetry.semconv.trace.SpanAttributes` (previously subclassed here)
    is deprecated since semconv 1.25.0, and the *stable* http module renamed
    the keys (e.g. `http.request.method`), so only the incubating module keeps
    the original `http.method` / `http.url` / `http.status_code` / `db.*` values.
    Sourcing from it keeps emitted span attribute keys unchanged.
