H100 does have NVDEC and jpeg ingest accelerators

Tbh it’s mildly surprising they even removed NVENC considering the overall size of the chip (in the absolute we are only talking about low-single-digit mm2 savings) and then H100 is still advertised and has features targeting VM graphics/visualization still… remember they also still put a full graphics pipeline with ROPs/TMUs on the chip, just no actual display hardware.

It's a tradeoff with verification and validation, not so much die-space. If you include the IP, you need to run an expensive (time-consuming) simulation and emulation for the IP. Then, you need to validate it on first silicon and pray that it doesn't impact yield in HVM.

These days, simulation runs basically nonstop on all the FPGAs the company is able to throw at it until tape out. Then, in post-silicon validation, you have engineering teams working 24/7 to validate the device on the bench. Finally, test engineering tries to achieve yield in HVM.

Anything that you don't need on the spec sheet or the designer insists on is cut to save time to market.

These can also be used for machine learning actually (see Dali for data loading for instance)
