It is a standard,

https://www.ecma-international.org/publications-and-standards/standards/ecma-372/

As for why it isn't in ISO C++, for the same reason most GCC and 
clang extensions aren't in ISO.

No one has bothered to endure the work and the voting process to 
make it part of ISO, including Microsoft that published it via 
ECMA.

As for why no other has adopted it, it really only makes sense 
for bytecode based stacks, and there is no competition to CLR for 
low-level languages.

WebAssembly is the one that came closest, and they still don't 
have a GC story to talk about.
