Hmm... I might blindly assumed, that all actions listed in phpactor.nvim are missing LSP implementation. Namely:

PhpActor [
  class_inflect
  context_menu
  expand_class
  generate_accessor
  change_visibility
  copy_class
  import_class
  import_missing_classes
  move_class
  navigate
  new_class
  transform
  update
  config
  status
  cache_clear
  copy_fcqn
  lsp/status
  lsp/reindex
  lsp/debug/config
  lsp/debug/config
  blackfire/start
  blackfire/stop
]

But it seems it is only true for change_visibility, generate_accessor and navigate maybe.

yeah, some of those are LSP actions.

fwiw the ones that have no direct counterpart:

• class_inflect: i think this generates interfaces from classes
• context_menu: replaced by LSP
• change_visibility: technically still on the list to port to LSP, although tbh I never bothered as it's so easy to do.
• {move,copy}_class: There is some support for moving classes in LSP, although the "RPC" version does this on disk and I prefer it tbh.
• navigate: not really something that fits into vanilla LSP - could be integrated as a custom LSP action and have support provided in the client (e.g. phpactor-vscode)
