It is a struggle though to get the improvements through the committee. Especially the C++ folks from the Clang side fight very hard against it, this is - for example - why we not have forward declarations where I already had weak consensus, but the clang area team made it clear they will never implement it.

The vec macros currently there directly call realloc()… that's gonna exclude any custom allocator setups… and the string code uses the vecs :/
