I wouldn't be happy being there, at all. That being said, the A7 is a far more robust camera than people give it credit for. Three cases of failure do not a statistic make. I could counter with my own experience in the rain, as well as posts of photographers leaving theirs outside for timelapse in freezing weather, or shooting besides crashing waves, all without issues.
Also, good luck making Olympus cover water damage. Or any manufacturer, for that case.
These were just three random examples that popped up on a Google search front page, I've come across plenty more, but haven't saved any links. If your gear is sufficiently weatherproof, like my E-M1, I don't need water cover damage. And if the camera happened to disappear underwater, then I have insurance.
When I bought my E-1, the camera store had a stand at an exhibition and had set up a fountain with a small waterfall on it. All that week, the salespeople would hold the camera under the waterfall for several minutes, dry it off with a towel and then take shots. That convinced me to get the E-1.
As an additional example, many years ago, I had a camera bag fall into a river while out in the mountains. Inside that camera bag were a 50-200mm lens, two tele-extenders, and I think an 11-35mm lens. After I pulled them out of the water, emptied the water out of the camera bag, dried the lenses off with a towel and let them stand in the sun for final drying, all were in perfect condition and never failed me in the many years that I owned them.
A lot of people talk about how weatherproof their brands are, but usually cover them up at the first sign of a light drizzle. The only other brand that I know that are as weatherproof are the Canon pro cameras and lenses. I've stood side by side with users at football games and, other than myself, they are the only ones that don't cover their gear with raincoats.
