It's the new revised ELF specification which we developed over the
last year and a half. It's not yet publically available.

You can put .hidden in it's just that the ld.so's before glibc 2.2
won't recognize it. Therefore a check for gas is sufficient. But the
behaviour you will see might not be what you expect. Therefore you
should look for other means to make a smbol unavailable. E.g., by
using a symbol map.
