how can it be marketed as a step forward compared to having the React pages interact with any kind of back end through reasonably standard web services?
With RSP you can implement a server function and (relatively) directly call it on the server, type-safely. Try doing that another back-end (I have and mostly failed).

Sounds like a potential foot-gun for input validation by the backend getting missed. :(
Isn't that the purpose of tRPC?
