yes, so a TD saying exhaust can't be "reingested" means: That's for all intents and purposes the rule now.
I think the RB8 exhaust is not the silver bullet they had in last year's EBD. All teams can reproduce it without a whole lot of difficulty.( or at least not a lot of difficulty by F1 standards)I think this year we'll be back to traditonal aero work(non-exhaust, non f-duct, you know: wings n stuff) being the main performance differentiator. Especially controlling the vortices off of the front wing and using them to good effect. Also I think a lot of the aero development will be small iterative geometry changes that we'll probably miss more than we catch.
Also the regs all but stifle diffuser development, both geometrically and because this tiny weak diffuser will be hard to pull real gains out of
