Recent release introduced a feature [E2E tracing](https://github.com/googleapis/nodejs-spanner/pull/2202) which added the global propagator [here](https://github.com/googleapis/nodejs-spanner/blob/main/src/instrument.ts#L125) This should not be added as default in the SDK instead customers should add it. ### A step-by-step description of how to reproduce the issue, based on the linked reproduction. 1. Enable E2E tracing as per sample [observability-traces](https://github.com/googleapis/nodejs-spanner/blob/main/samples/observability-traces.js) 2. Add Context propagation using any other propagators `propagation.setGlobalPropagator(new CompositePropagator()());` 3. Propagators will be overwritten ### A clear and concise description of what the bug is, and what you expected to happen. Propagators should not be added as default. This is a breaking behavior for customers already using propagators This is recent change in [7.17.0](https://github.com/googleapis/nodejs-spanner/releases/tag/v7.17.0)
