It certainly is. Ride without a headlight and that cannot happen to you. Ever.
But that was just an example - there are plenty more.

I also don't believe that misunderstood 'apparent' headlight flashes are a significant cause of crashes.
I don't believe they you know that to be true. There certainly are lots of ROWV's with motorcycles, the majority of which are riding around with headlights on these days. IF DRL are supposed to work why have ROWV's not diminished to just 30% (or whatever) of the biking population?

On the other hand we do know that SMIDSY (Sorry mate I didn't see you) is a common effect. Many believe - for various reasons, of which some are good - that showing a headlight is helpful for bikers in daylight conditions.
Are you seriously suggesting that bikes with DRL suffer from
LESS SMIDSY's?
The effect of Risk Compensation needs to be considered too - have you read Risk by John Adams? IMO all road users need to pay great attention to the effects of believing you are safer when you are not.

Now I'm no fan at all of permanent daylight running lights for any vehicle, but it is definitely the individual driver's (and rider's) right to assess conditions and choose. Some choices will be tragically wrong on both sides.
Once you realise that you can be seen in good daylight with your lights off there can be no good reason to use headlights in those conditions - only problems from doing so. My example was just one of those.
Don't go off on one of your rants at me. I'm definitely not in the mood for it.
Whatever you may think, there is no 'one clear answer' to the question of motorcyclists choosing to use daytime headlights. It's a complex issue with good arguments on both sides.
Every biker has to make an individual decision and the wise ones will probably vary that decision depending on circumstances. Where mirror visibility is the most important aspect, showing a headlight increases practical visibility substantially.
