Yeah, and as others have pointed out already, many existing interactive terminal programs handle SIGINT in this way. E.g. programming language repls interrupt running code and return to the top level prompt. E.g. mutt (SIGINT will cause mutt to politely asks if you want to exit before doing so).

I think of it this way: we have both SIGINT and SIGTERM for a reason. One "interrupts" and the other "terminates" and there are often good reasons to handle "interrupt" differently from "terminate" -- at least in interactive programs.
