OK, Then I assume the critical thing is that dynamic arrays
memory is
not part of the array itself. But is this a deal breaker?
A deal breaker for what? For making sizeof return the amount of
memory allocated? Yes. It's the same behavior in C and C++:
float verts[3];
assert(sizeof(verts) == (sizeof(float) * 3));
float *verts = malloc(sizeof(float)*3);
assert(sizeof(verts) == sizeof(void*));
