Why the emphasis on RVA23? Since when are vector instructions a minimal necessity? Plain RV64GC is mooore than powerful enough for industrial/machine controllers & the like - assuming a standard sw/hw platform.
What's missing here is the "made in Europe" bit. Currently (very few exceptions), RISC-V SoCs are designed by Chinese companies, maybe fabricated in Taiwan, and boards they go on manufactured in China.
Imho that is what Europe needs to address. With EU-made boards available, the software side is the easy part.
There is some European CPU initiative. Sounds great but where are the boards?
