I barely ever spin out on 50/11, and when I do, it's because I've just cycled up a big hill and am going down the other side at 60kph. So I'm usually glad to rest my legs. What's more this is the UK so there are cars, sharp turns, rain water, gravel and potholes everywhere, and on most roads I feel like I'm taking my life in my hands above 60kph. I would rather concentrate on braking and avoiding hazards than trying to pedal at 110RPM. And finally, in my experience the dude who's tucked up at 60kph is going faster than the dude who's still trying to pedal in a normal position.
Safe to say I personally don't give the slightest shit about top end. If I lived somewhere with 20km smooth tarmac descents and no cars maybe I'd change my tune.
Edit: just remembered I have some Deore triple cranks, might swap those on. They are absolutely hideous though:
Maybe with new chainrings they'd be alright

Exactly, as long the person don't mind it being a little ugly without the chainguard, it work perfect.
@frankenbike chainline actually not an issues, as on a triple, the middle is the middle, so you can ride on the smallest sprocket and the biggest and still not worry about cross chaining.
Now, with the small 30t, you're never gonna go 30/11, as that not even enough to go fast, you're likely to use it for climbing a hard hill, as you can probably be able to climb a normal hill with 46/28t, this ratio is very similar to the old road-race combo of a 39/23t.
46/32 is almost a normal climbing gear (37GI, a 34/28 is 32GI).
Only downside? 46/11 spin out easily, but it's a gearing you use everyday, not for racing in a group.
