Yeap, Type 100 isn't even called IFV in Chinese , it is called support vehicle (支援车).
In context , for English the accurate term will probably be tank companion,
Though it unlikely that we will get a Type 100 chasis based IFV just for the weight , for fuel logistics reasons a 40t IFV just will cost to much fuel to run, runing a armored force that is 100% made off 40t platforms are not economical.
let say you do want a 100% 40t platforms,for every tank you need about 1.5X IFV , for every tracked vehicle you need 3X in trucks.
It would mean giving each armord brigade about twice as much trucks just to keep the force supplied, that would make a armord brigde with around 600 8wheelers,instead of 300-ish 8 wheels trucks that a ABC have today,the trade off is just not worth the cost.
These day a armored force is about 60% IFV and IFV based utility tracked vehicle, and only 30% tanks.
IFV still need to be it's own 20t-25t chassis , but that IFV sure can take alot of the technology that Type 100 has , like maybe a scaled down version of the Engine.
