> I would say modern c++ written by someone already familiar with rust will probably be structured in a way that's extremely easy to port because you end up modeling the borrow checker in your brain.

I can't stress out how much important this sentence is. I would even remove the "familiar with rust" part.

Anyone who still thinks it's good to use C/CPP on modern hardware where Rust support is available and good: please print the sentence above and post it all over your place.
