Agreed. But any DSLR shooting RAW still requires the user to gauge a scene while shooting and dial in compensation. Get it wrong and any sensor from any brand will blow the highlights.
We've never had it so good for these adjustment, right there at our fingertips. But knowing which ones to use when, that's the tough part. But it always has been in photography. Frankly, part of photography has always been that shadows can still be pitch black and the sky is white, white, white..but who's looking when the rest of the composition is accurate.
Also, there's filters, the DA 15 Ltd., all sorts of methods to curl back blown highlights before they happen. It sounds like you may need an ND filter or similar.
And there's a difference between high contrast and blown highlights.
