General question on adopting RISC-V cores

Can anyone give a summary f challenges for adoption embedded controller vs. Application Processor. Here’s my take based on my limited exposure to risc-v

• Development on application processor is more recent
• There are less options for application processors
• eco system has more evolved around embedded controllers
• Just as ARM has higher entrance barrier to replace x86 on high end processors, it will take longer for risc-v to replace ARM on application processors and develop the corresponding eco system around it.
