Not an expert on std::format to know how we could achieve the same without a hard dependency (if possible).

It's going to be possible after P3070 https://www.open-std.org/JTC1/SC22/WG21/docs/papers/2023/p3070r0.html by defining a function `format_as`, but that's C++29. By then, I sincerely hope that we would have mostly moved to C++17 and the point will have been made moot.
