I can think of one valid use case for this unsolved by any other solution:

Lets say a company has an SoC board base product currently currently base on ARM. They want to eventually migrate to RISC-V based solution.

If a company has a product currently written to use ARM compiled code, but wants to transition to RISC-V (which isn’t ready yet), they could deploy this board which could run today’s ARM implementation, and it would be future-ready when the RISC-V implementation would be released without having to replace hardware.
