This issue is related to the proposal of promoting maturity of experimental and preview feature commands and flags #1771

The --platform flag was introduced to several ORAS commands oras attach. It is currently marked as Preview.

Rationale for Promotion

Over recent releases, the flag --platform has demonstrated:

• Functionality completeness – The feature has been used in the core use cases of specifying certain platform of the image
• Stability – syntax and output structure have remained consistent over multiple releases.
• Low maintenance overhead – No major breaking changes or regressions reported in recent cycles.

Given its maturity and stability, promoting --platform to Stable will encourage broader adoption while signaling to users that the feature is nearing full stabilization.

Next Steps

• Update the feature mark from Preview to Stable in CLI documentation and help text.
• Communicate the change in release notes for ORAS v1.3.0.

If you agree with this proposal, please vote on this issue with your comments. Thanks
