-TODO: Update the following paragraph with new strategy for managing compatibility
-
-This repository publishes `-alpha` artifacts and as discussed
-in [opentelemetry-java/VERSIONING.md](https://github.com/open-telemetry/opentelemetry-java/blob/main/VERSIONING.md),
-we make no compatibility guarantees. However, by convention we've been keeping attribute constants
-around with `@Deprecated` annotation while we work towards formalizing the strategy (
-see [#6](https://github.com/open-telemetry/semantic-conventions-java/issues/6)). The process for
-retaining removed attributes is to carefully add entries to
-the [SemanticAttributes.java.j2](./buildscripts/templates/SemanticAttributes.java.j2) template. This
-is meticulous and error prone, hence the desire to fix it. To ensure we don't accidentally delete
-any constants while we work our a permanent
-strategy, [japicmp](./buildSrc/src/main/kotlin/otel.japicmp-conventions.gradle.kts) has been added
-as a build check. It will ensure that only binary / source compatible changes are made. **NOTE: this
-checking of binary / source compatibility is not required and will change in the future.**
-
-To check compatibility, run `./gradlew build` after updating the template and running the generation task as documented above.
