Perhaps, but I suspect they don't care about that. Fewer modules reduces assembly and interconnection complexity, so it seems like a natural evolution to me. They probably don't care about having to replace more cells in a single-module repair replacement, because they just replace the whole pack anyway.This might have been partly a deliberate effort on Tesla's part to keep people from easily reusing(and abusing) Mod 3 modules.
I've wondered the same thing about most EV packs (Leaf, Golf, Bolt...), since they are all basically flat plus lumps under seats, and often include at least some of these supporting components. Because there is only one lump on this one (at the back for support components), it might be a simpler and thus particularly good candidate.I wonder if the whole pack, possibly with the electronics hump, could be used under larger vehicles, like your van?
I'm picturing a compact pickup truck with the pack under the rear part of the cab and front part of the box, but since large packs are quite wide, the truck would need a custom frame (not the traditional ladder frame with nearly parallel rails).
