 ## Removal Checklist
 
 - Confirm supported .NET runtimes and administrator packaging guidance no longer require accepting backslashes in enterprise ZIP entry names.
-- Replace the manual enterprise configuration plugin ZIP extraction with `ZipFile.ExtractToDirectory(...)`.
-- Remove `ExtractConfigPluginArchive(...)`, `NormalizeConfigPluginZipEntryName(...)`, and `GetConfigPluginZipEntryDestinationPath(...)`.
+- Replace `PluginArchive.Extract(...)` with `ZipFile.ExtractToDirectory(...)`.
 - Update this document's status to `Removed`.
