I didn't follow why emit a warning for this?

I think its important to draw attention to the fact that the contents of the file don't reflect the configuration of the SDK. I imagine the workflow being something like:
- Include an overriding environment variable
- Receive a warning that the configuration file is different (warning doesn't mean a problem in this context - more like a notification): "Environment variables were set that overrode the configuration specified at /path/to/config.yaml"
- If opted in, log the entire effective configuration after applying overrides so you can deduce what changed

I'd suggest limiting this to a debug message. It could be worth looking at Spring for prior art.

That's fine. I can relax the language to say "The implementation SHOULD emit a log if calling Merge Environment results in change...". Leave it to implementations to decide the appropriate log level.

@marcalff unfortunately running a separate process is a non-starter for many end user environments that OpenTelemetry needs to support. |

If set other environment variables defined in this file are ignored.
It needs to be clarified in which file will the environment variables be ignored. The file defined in OTEL_CONFIG_FILE?

Resolves #3752.
An alternative to #3805 which ignores the existing environment variable scheme, and leaves a placeholder for defining a new environment variable scheme specific to file configuration, with names derived from the configuration model.
This is the proposal I suggested here. To restate the advantages:
To understand exactly what a refactored configuration model might look like, I've put together open-telemetry/opentelemetry-configuration#69 to review along side of this.
