      name = "Pending mode operator"
    },
    mode = "x",
    noremap = true,
    nowait = true,
    silent = true
  }

  -- Suggested Spec:
  {
    { "ga", group = "Pending mode operator", mode = "x", nowait = true, remap = false },
  }

This appears to be caused by text-case.nvim calling whichkey.register, which is deprecated. Instead, text-case.nvim should call whichkey.add when available.
