Though the author doesn't look to be trying to write a great tutorial, rather prioritizing sharing what and how they learned something from their perspective.
Please stop smashing all the nuance out of compiler diagnostics this way.
One of the biggest successes of Rust has been its great diagnostics and I can assure you that it would not help to smash my Clippy lint suggesting that what I wrote looks a lot like an implementation of the addition operator† into a fatal error like the one I get for forgetting to initialize a variable.
Rust even has a (begins empty) diagnostic category [named "expect"] for "This warning should be here" which will flag cases where a notable thing not only might happen here and if it does we can ignore that, but if it's no longer detected that is itself suspicious and should be diagnosed.
† Yes it does Clippy, and I considered implementing Add but I had a good reason not to, so here is a suppression annotation.
C got lint in 1979, and is incredible how much advocacy is still required for folks to use the tooling their compilers offer out of the box.
This problem isn't even C specific, other ecosystems suffer from similar adoption issues.
Requiring all of them to adopt common linting rules at the same time is infeasible.
Also, it’s not true that linting rules never become part of the compiler. For example, the original lint (https://wolfram.schneider.org/bsd/7thEdManVol2/lint/lint.pdf) states
“The type-checking rules also require that, in structure references, the left operand of the -> be a pointer to structure”
and mentions warnings on such statements as
int i 1;
i =- 1;
In some circles having the compiler dictate the way, and only true way, is seen as straightjacket programming.
But this illustrates how absurd the discussion is nowadays. Incrementally making things stricter and fixing warnings along the way is one of the most cost efficient way to improve quality and safety. Rewriting the software one of the most expensive. So if the former is rejected because the burden is too high, then obviously the overall aim to make things safer can not be too important and the push for rewrites must partially be motivated by other interests.

At a moment he mentions a trick he played on JPL folks, his static analysis tool, instead of showing all the issues found, would only display the top 10, without telling them there were actually more than 10.
So they felt motivated to fix them, it were only 10 after all.
Naturally eventually they became aware of the trick.
Or if you turn your argument around: if people depend on workflows and automation (I do of course too), then this is a good reason to standardize the diagnostics and errors of the checking tools to the point where the workflows and automation can depend on them. Otherwise they will remain tools which are completely optional to run, or even worse, are not part of your normal work flow.
However, like in any ISO languages, that only happens if enough people vote for it, and someone is willing to submit a paper in first place.
Tribalism is sooo ... sadly now.
Please don't.
