That one is dubious. Char has magic aliasing properties that uint8_t might not have (iirc that was contentious in a GCC bug report) and it will be signed on some platforms and unsigned on others, which changes implicit integer conversions.
Missing from this is to embrace attribute((overloadable)) and attribute((cleanup)).
Overloadable is the sane, useful alternative to the thing standardised as _Generic. The C _Generic will let you define an overload set, with some weirdness around type conversions, provided you write the entire set out as a single _Generic expression, probably wrapped in a macro. If you want to dispatch on more than one argument, you nest _Generic expressions. If you want to declare different functions in different headers - maybe you want 'size(T)' defined on various types in the codebase - you can't. If you don't like the idea of thousands of lines of distracting nonsense in the preprocessed output, tough. Or - use overloadable, get open overload sets, minimal compile time cost, obvious intermediate IR, everything works. Prior art is all of C++, so talking decades of the tooling learning to deal with it.
Cleanup is either a replacement for raii, or a means to have debug builds yell at you when you miss a free. It looks like that got warped into a thing called 'defer' with different behaviour that didn't make it through the committee last time.
Other than that, ad hoc code generators work really well with C. Especially if you're willing to use some compiler extensions. Code generators + overloadable will give a fair approximation to templated data structures without going deep into the insanity of the preprocessor. If the overloadable functions are static inline forwarding things in a header they don't even mess up symbol names; you just get a straightforward translation to vector_float_size or whatever.
Personally I've given up on ISO C. I'd quite like to code in a dialect of C99 with a few of the GNU extensions and the equivalent of `fno-strict-aliasing`, but C with the pointer provenance modelling and an accretion of C++ features has no personal value. Currently still using clang with flags to make it behave like that but I'm conscious that's on borrowed time - the application performance friendly aliasing rules are the default and gaining popularity, and relying on opt-out flags is a means of opting into compiler bugs.
Semi-actively seeking something that will let me write assembly without the hassle of manual register allocation and calling conventions. Old style C with some of the warts bashed off would be good for that.
