I wonder why C doesn't just disappear then? As every C program, with
some tweaks as necessary, will compile as C++.

But C++ is complicated, and above you suggest that has not stopped it
being successful!

Most of the MISRA examples you gave involved constants, which I said
elsewhere are an easy feature that ought to be built-in to the language.
The others are:
#define PLUS2(X) ((X) + 2) /* Macro expanding to expression */
Inline function. (That such macros remove the need to specifier type is
something that needs thinking about, perhaps as a new language feature,
but which must under no circumstance involved introducing templates).
#define STOR extern /* storage class specifier */
Redefining the language (wasn't this prohibited?).
#define INIT(value){ (value), 0, 0} /* braced initialiser */
IMO, also redefining the language (even if it is a new version of C). An
initialiser with multiple elements is enclosed in {...}. This gets rid
of the braces.
#define CAT (PI) /* parenthesised expression */
Inline function.
#define READ_TIME_32() \
do { \
DISABLE_INTERRUPTS (); \
time_now = (uint32_t)TIMER_HI << 16; \
time_now = time_now | (uint32_t)TIMER_LO; \
ENABLE_INTERRUPTS (); \
} while (0) /* example of do-while-zero */
Inline function.
So you can go through programs and look at how macros can be eliminated.
For new code at least, because you need to support existing code.
If your intention is to enforce macro usage guidelines, a bit like
MISRA, to make it easier to analyse code, then that's simpler in that
you don't need to create a new language!
