It's not always clear that it's referring to an implicitly generated move ctor. This results in difficult to understand errors such as:
In file included from ../../chrome/browser/task_manager/sampling/task_group.cc:5:                  
In file included from ../../chrome/browser/task_manager/sampling/task_group.h:21:                  
../../chrome/browser/task_manager/sampling/shared_sampler.h:41:10: error: [chromium-style] Complex constructor has an inlined body.
  struct SamplingResult {                                                                          
         ^

wez and I were guessing which ctor this was complaining about until we just guessed wildly.
