Why are OTEL_{SIGNAL}_EXPORTER exclusive to Python?

[KennethHoff]

My team has been working on implementing OTel and Aspire in our Python app and in doing so we noticed the OTEL_LOGS_EXPORTER (and friends) environment variables. We looked them up and they were the standard so we used them as the marker for whether to use Azure or otlp. Later when we were starting to add OTel to another app we noticed that we didn't get these environment variables for JS or C#. We ended up adding them manually, but it got me wondering;

Why are these environment variables exclusive to AddPythonApp and not in WithOtlpExporter directly?
