LogData does not serve any specific purpose besides adding instrumentation scope to theLogRecord.
It would be more efficient and easier to use if SDK version of theLogRecord included instrumentation scope and was used directly by the processing pipeline.

Spec allows this via

The SDK may also use a single type to represent both ReadableLogRecord and ReadWriteLogRecord.

https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/sdk.md#additional-logrecord-interfaces

Specific changes:

• SDK implementation of theLogRecord should have instrumentation scope property
• SDKLogger implementation should populate instrumentation scope on the log record when it's created or emitted
• LogRecordProcessor.on_emit should takeLogRecord as a parameter
• LogExporter.export should takeSequence[LogRecord] as parameters
