Refer to getsentry/sentry-docs#15127 for discussions on why this change was made.
tldr: We will consolidate sentry.origin for Logs according to the new specs:
From the updated docs:
Logs can be generated in three ways:
- 
User calls Sentry’s Logging API directly: SDKs MUST NOT send a sentry.origin. As logs are charged based on size, we want to minimize the size of logs, and we intentionally deviate from the original Trace Origin documentation. 
- 
Captured from a logging library: Use auto.log. format. where  is the relevant integration. For example, the .NET Serilog library emits: 
{ "sentry.origin": "auto.log.serilog" }
- Auto-emitted logs from other instrumented systems: Use the auto.. format as outlined in Trace Origin documentation.
{ "sentry.origin": "auto.db.prisma" }
Thank you! 🙏
