Couple of small comments, but a good start and something we can iterate on.

Thanks!

In the future, we might consider adding opt-in logging to print the out change in the model after each stage of customization, but I'm happy to come back to that type of thing later. This is a good start!

Just realizing that this is going to be a problematic contract from a packaging standpoint..

  • Currently, the SPI lives in opentelemetry-sdk-extension-incubator
  • In the future, we'll want to move it to opentelemetry-sdk-extension-autoconfigure-spi with the rest of the SPIs
  • That leaves a thorny question for where OpenTelemetryConfigurationModel and the rest of the data model lives. First guess would be opentelemetry-sdk-extension-autoconfigure, but that creates a dependency cycle. They could live in opentelemetry-sdk-extension-autoconfigure-spi, or opentelemetry-sdk, or opentelemetry-sdk-common, or some new opentelemetry-sdk-config package.

Idk, let's cross that bridge when we get there.
