But freestanding is not experimental, unlike Embedded Swift according to Apple. And there are full, large OS kernels written in C and C++.

You continue being undeniably, completely wrong.

But at least a lot of tasks in a kernel would require something else than reference counting, unless it can be guaranteed that the reference counting is optimized away or something, right?

Even kernel development? Do you know of kernels where reference counting is the norm? Please do mention examples.

The practical reality is arguably more important than beliefs. Apple has, as it turns out, invested in trying to make Swift more suitable for kernel and similar development, like trying to automate away reference counting when possible, and also offering Embedded Swift[0], an experimental subset of Swift with significant restrictions on what is allowed in the language. Maybe Embedded Swift will be great in the future, and it is true that Apple investing into that is significant, but it doesn't seem like it's there.

And considering Apple made Embedded Swift, even Apple does not believe that regular Swift is suitable. Meaning that you're undeniably completely wrong.
