Is your feature request related to a problem? Please describe.

OTTL has seen extensive use via the transform processor, filter processor, tail sampling processor, routing processor, count connector, and routing connector. Although there is a few items to address, breaking changes are slowing down. I believe the package is close to Beta stability.

Items to address:

• [pkg/ottl] Add godoc comments to everything #28893
• [pkg/ottl] expose a parser explicitly for parsing conditions #13545
• [pkg/ottl] Add an error mode to ignore errors and silence warnings #22743
• [pkg/ottl] Validate that all parts of a path are used by a Context #22744
• [pkg/ottl] Validate that all parts of a Key are used by a Context #30051
• [pkg/ottl] Express context cache as a map[string]any. #26108
• [pkg/ottl] Allow users to specify the format of the hashed replacement string in the replace_pattern* editors #27820
• [pkg/ottl] Create "e2e" tests in the package #28642
• [pkg/ottl] Ensure public API allows hierarchical optimizations #29016
• [pkg/ottl] Update statements to reflect their context #29017
• [processor/transform] Create new metrics from existing ones #16221

This is an initial list, but not exhaustive - it may change over time.

From the stability levels documentation and referenced issues, it sounds good to me. 👍

Is there any update on this?

@edmocosta is actively working on #29017 and has been for quite some time as it has been a hard one to solve in a backwards compatible way. This is likely the last big thing before beta.
