I know what you mean and I know people err against it, but at the end of the day the manufacturer would not tell you you can do so in your handbook if it was a big no no!
Plus, again, if you bump start properly it starts first time anyway, so it's no worse than turning an engine over on the starter which won't fire, same principle of unburnt fuel!
As I say it's never caused me or anyone I know any harm!
