High-Level Assessment

The following are alternative approaches to this PR:

1. Keep a deprecated no-op gate (alias) for 1+ releases

• ➕ Avoids breaking clusters or automation that explicitly enables/disables VSphereMultiDisk in custom FeatureGate configs
• ➕ Allows a cleaner migration window with warnings/alerts before hard removal
• ➖ Prolongs maintenance of a gate that no longer affects behavior
• ➖ Can create confusion about whether the gate still does anything

2. Remove gate but add explicit upgrade/release note guidance

• ➕ Keeps codebase clean while still managing user expectations
• ➕ Low implementation overhead compared to maintaining compatibility logic
• ➖ Does not prevent hard failures if unknown feature gates are rejected during validation
• ➖ Relies on users noticing and acting on documentation

Recommendation: The PR’s approach (full removal) is appropriate for a GA-by-default feature, but confirm the upgrade/validation behavior for user-specified FeatureGate configs: if unknown gates are rejected, consider either (a) a short deprecation/no-op window or (b) clear upgrade notes and any necessary guardrails so upgrades don’t fail when VSphereMultiDisk is explicitly listed.
