nah - who else has released shit like this recently? Most Grime MCs are sticking to proper grime.
In Stormzy's case I think he genuinely loves this kind of sappy pop/r&b stuff, he's not doing it to sell more records. Which is why I low it. When you've got tunes as good as Cold, Mr Skeng, Big for Your Boots & Return on the Rucksack you can do what you like with the rest of the album.
