Kustomize

  • No packaging or distribution story, which is exactly what Helm charts provide
  • Deeply nested overlays become hard to follow, and reasoning about the final output requires building it
  • No release lifecycle: nothing tracks what is installed or supports rollback the way Helm does
  • Patch syntax is fiddly for anything beyond simple field replacement

Mozilla Firefox

  • No longer supported on Windows 8.1 and earlier versions (users must use Firefox ESR)
  • No longer supported on macOS 10.14 and earlier versions (users must use Firefox ESR)
