The "core systems of Linux" include the Linux kernel, openssh, xz and similar libraries, coreutils, openssl, systemd, dns and ntp clients, possibly curl and wget (what if a GET on a remote system leaks data?),... which are usually separate projects.
The most practical way to establish some uniform governance over how people use those tools would involve a new OS distribution, kinda like Debian, Fedora, Slackware,... but managed by NIST or equivalent, which takes whatever they want from upstream and enrich it with other features.
But it doesn't stop here. What about browsers (think about how browsers protect us from XSS)? What about glibc, major interpreters and compilers? How do you deal with random Chrome or VS Code extensions? Not to mention "smart devices"...
Cybersecurity is not just about backdoors, it is also about patching software, avoiding data leaks or misconfigurations, proper password management, network security and much more.
Relying on trusted, TS cleared personnel for OS development doesn't prevent companies from using 5-years old distros or choosing predictable passwords or exposing critical servers to the Internet.
As the saying goes, security is not a product, it's a mindset.
We wouldn't have to change the structure of the project to ensure that everyone is trustworthy.
As for applications beyond the core system, that would fall on the individual organizations to weigh the risks. Most places already have a fairly limited stack and do not let you install whatever you want. But given that the core system isn't optional in most cases, it needs extra care. That's putting aside the fact that most projects are worked on by big corps that do go after rogue employees. Still, I would prefer if some of the bigger projects were more secure as well.
Your "mindset" is basically allowing bad code into the Kernel and hoping that it gets caught.

Not at all. I'm talking about running more and more rigorous security tests because you have to catch vulnerabilities, 99% of which are probably introduced accidentally by an otherwise good, reliable developer.
This can be done in multiple ways. A downstream distribution which adds its own layers of security tests and doesn't blindly accept upstream commits. An informal standard on open source projects, kinda like all those Github projects with coverage tests shown on the main repo page. A more formal standard, forcing some critical companies to only adopt projects with a standardized set of security tests and with a sufficiently high score. All these approaches focus on the content, not on the authors, since you can have a totally good-willing developer introducing critical vulnerabilities (not the case here, apparently, but it happens all the time).
On top of that, however, you should also invest in training, awareness, and other "soft" issues that are actually crucial in order to actualy improve cybersecurity. Using the most battle-tested operating systems and kernels is not enough if someone actually puts sensitive data on an open S3 bucket, or if someone only patches their systems once a decade, or if someone uses admin/admin on an Internet-facing website.
