To be fair, it was an incredibly vague rumour. I've certainly never seen it substantiated, and Carver has always written really good Sam&Dean. If you wanted a change in direction, I'm not sure he'd be the choice for show runner. (Also, Jensen said he trusted him, and Jensen seems to be a firm believer in the brotherly bond.)
Added to which, the time for scaling it back was a couple seasons in. Doing it seven years in would be pretty weird.
