It's not bending the language, the standard has nothing whatever to say

The thing is, the standard does not read "An identifier which has
previously been defined by a #define directive shall not be redefined
by another #define directive except as the same type of macro and with
the same replacement-list". If it did, I would agree with you.
Instead, it reads "An identifier CURRENTLY DEFINED ... shall not be
redefined by a #define directive" (emphasis mine). The intent is,
IMO, clearly to forbid (non-redundant) redefinition no matter how the
identifier acquired a macro definition in the first place - whether by
another #define, or by being built-in macros, or by -D.
