You’re arguing it’s a rhetorical misstep and at the same time suggesting it need not be called out. Huge pet peeve of mine is when these little flourishes derail an entire discussion because they aren’t really true but get the sympathetic individuals involved all riled up. If the device isn’t positively contributing it should be identified and dismissed.
It only 'derails' anything if someone decides to pedantidunk on it. That's not conversation. The occasional flight of verbal fancy is, though. 'Calling out' completely mundane things about other people's comments demolishes forums which is why the site docs and zillions of mod comments exhort you not to do it.
