1. Cores already exist or are coming that satisfy the existing platform. They would be obsoleted by a change in the requirements.
2. RV64GC is already quite big. Piling more requirements onto it will make it harder to introduce small cores.
3. V is pretty complex and I don't agree with your assertion. In contrast I'm aware of cores with vector where the vector part takes up 50% of the die and does exactly nothing for the scalar apps that don't use it. I'd much rather spend that silicon on more IPC or a 2nd core.
