node_revision_delete_protection
Node Revision Delete Protection provides granular control over revision pruning by allowing users to protect specific, individual revisions from being purged by the Node Revision Delete module.
In many workflows, you may want to delete hundreds of minor "typo-fix" revisions but keep specific "milestone" versions (such as a version approved by legal or a major content overhaul). This module ensures those selected revisions remain in the database, even if they fall outside your global age or number-to-keep settings.
Use Case:
Imagine you have a page with 100 revisions. You want to keep only the last 5 revisions globally, but Revision #12 was a version specifically approved by your board of directors. With this module, you can "protect" Revision #12 so it stays forever, while the other 94 unnecessary revisions are safely deleted.
