Summary

The Laminas organization has a relatively straightforward support policy of not supporting any version that depends on a PHP release that is EOL'd:

• https://www.php.net/supported-versions.php
• https://github.com/laminas/technical-steering-committee/blob/c7f6babfb1773d9cb9371208102cbb8b27980bd5/meetings/minutes/2020-03-02-TSC-Minutes.md#lts-policy

This means that, based on supported-versions.php (or similar database), we can automatically delete branches with X.Y.x naming, and all their associated open milestones, when the PHP version goes EOL.

Since this is laminas-specific, and not really pertinent to release automation per-se, it may be a concern for a different tool, or a specific action within this tool.
