In other words, once in 11 years.

Because GCC developers, like the proponents of inline namespaces, forget that 
libraries use their libraries and thus expose their ABI differences in their 
ABI. GCC devs invented the "abi_tag" attribute so they could mark methods 
according to a deveoper-defined tag, and propagate that tag. They provide both 
sets of ABIs in libstdc++.

But unless developers of downstream libraries take the precautions to provide 
them both in their own libraries, this causes a BC breakage. THAT was the 
issue.
