Seriously, there is requirement to CPU draw UI components too ? OP didn't say that and it sounds crazy anyways. Even your point-of-sale terminal units with displays have integrated GPUs. Popular Ex in 2025: Qualcomm Snapdragon 810 SoC (octa-core ARM) with Adreno 430 GPU.
I mean if it requires a modern GPU, that leaves a ton of perfectly working older hardware out in the dust, even those with a GPU if they don't support modern APIs. That's a huge downside when the competing toolkits run just fine on the CPU.
