Would it be practical for the FreeRTOS plus libraries (like FreeRTOS+TCP) to be made submodules like the kernel?

I have been working with Rust bindings to the kernel, and the fact that the kernel is a submodule has made my task a lot easier.
I intend to write Rust bindings to FreeRTOS+TCP. If the same submodule approach were done for FreeRTOS+TCP, that would make this much easier as well.
