Yes, I do. But the unfortunate reality is that your "small change" makes your code much harder to work with for other people, since you are now writing a C derivative instead of standard C.

This is the same argument that was used when Microsoft launched Typescript. As it turns out, their strategy of extending an existing language to make it safer worked great, while brand new languages that are safer than Typescript are now miles behind it in terms of adoption. So it seems to be a pretty solid strategy, and if it brings people closer to a safe language, even if not 100% safe, it's still an improvement on the status quo.

Did it? Adoption seems to me to be a pretty silly metric given all the politics of language choice.

Given that the goal is getting C developers to adopt best practices, adoption is the most relevant metric here.
