The practical limit for battery capacity is 100 Wh; beyond that you need airline approval to travel with it. Apple's 17" Unibody MBP had a 95 Wh battery, and when that was discontinued the 15" rMBP offered 95 or 99.5 Wh until the Touchbar was added. If Apple were to reintroduce a 17" model, it could only offer 19% higher battery capacity than the current 15", which means it probably couldn't offer any better battery life.
I'd rather just see the 15" rMBP get a bit thicker so that it can have more variety of I/O and stay at the ceiling for battery capacity.

Does that also apply if it’s two batteries, both physically removable, from the outside? Just curious. SWMBO and I travel with can lights for diving, big batteries but none individually over the limit.
Yeah, it’s per battery. I usually carry two nearly 100wh battery banks. Never a problem. I imagine 100wh limit is what they’ve determined they can contain if it catches fire. I believe they also offer exemptions for slightly more with airline approval.
