um... nah.
My reasoning is based on safety and potential power capabilities when using it. For example, it's already gonna take a really healthy build (support 700+rwhp) to compete successfully in the 2.6 class. Now, to make it survive through all that PLUS spraying it. I'd have to assume more than a few trucks would be flirting with or surpassing 1000rwhp in this class. So no, that is certainly not needed in the 2.6 street diesel classes, at least not now. The classes may evolve into power like that with time and technological advances but it sure ain't there yet and doesn't need to be until the technology is there to properly and SAFELY support it. People will be blowing up more stuff if it's allowed and the more chargers, drivelines and engines that blow apart, the bigger risk we run of a puller or bystander getting seriously hurt or killed and that'll pretty much be the end of that.
so yeah, I say keep it off the pulling track IMO.
C-ya
p.s. exception maybe could be made for be an unlimited/open class but the safety rules have to be stringent and ADHERED to by everyone, not just the ones that are already mod trucks on #2. so a 2.8 or 3.o truck can't just strap the big bottles on and go out there and let 'er eat with the mod trucks unless they have all the safety items required for the class.
