Switching immediately to building with C++, and then migrating incrementally to safe forms in C++, would provide much more value per unit effort. It would also enable engagement by the orders-of-magnitude more available skilled C++ programmers, who could also pick up new skills writing modern, safe C++ to apply in other migrations.

It is not an either/or proposition. Certain, select modules could be recoded in Rust by particularly motivated Rust coders, leaving the huge amount of other code, for which there are too few Rust enthusiasts to work on, to be modernized in C++, and still able to call into the Rust code.

I think you may have misunderstood what the post is saying they're going to do. It is significantly more in line with your suggestion than you seem to think.

I might have misunderstood. But if so, good!

Yes, curl has a concept of "backends," which you can choose at compile time. This is about providing an option for a new backend, based on Rust libraries. That's it. Nobody is re-writing anything.
