@broadrun96 ...and there it is, folks.
We all knew that when the first announcement of the alignment between LMP1 & DPi rules that, eventually, Hypercars would be the odd-man out, even as they tried to include them. Cost & useability issues were going to push more manufacturers towards LMDh, where it's just powertrain that would determine the side-by-side comparisons.
The chassis manufacturers would hold the cards, not only with the first four but with others coming soon after, expanding the overall line of choice.
