The problem

I suggest adding a standard machine-readable marker to the GitHub release text that can inform services like rs-key-flasher that the user is recommended to increase the anti-rollback epoch.

Proposed shape

This can be done, for example, as a comment:

[0.4.10] - 2026-08-14

Release description.

Comment with marker (metadata is optional):
<!-- @increase-anti-rollback-epoch{"reason": "Important CVE-1234 was fixed"} -->

This is valid too:
<!-- @increase-anti-rollback-epoch -->
