Well one wouldn't want to help the trusting trust attack, one tries to defend one's self against it

Backdooring a compiler can be as simple as adding an optimization without fully understanding the impact
(See GCC optimizations + Linux kernel to see some amazing examples)

The Trusting trust attack is a very special case, where reading the source code doesn't allow one to discover the backdoor,
Because the backdoor is not in the source code but rather the digital providence of the compiler used.

Hence the important distinction and the difference between the two different projects, despite many shared tools and techniques.

Reproducibility is about, well, being able to reproducibly build software.
Bootstrappablility is about building digital provenance for our software
