Yes, this is officially approved. The gABI committee runs mostly on
consensus, but as a representative for Xinuos, I can offer the formal
stamp of approval.

I am under contract with Xinuos to maintain the ELF standard, and I
have converted it from raw HTML to ReStructuredText format, with the
goal of placing it into a github repository. That last part is not yet
done, but as soon as I can, I'll make an updated version of the spec
available. Until then, you'll need to reference the June 2013 version,
with various gABI discussions to serve as amendments. As another
quasi-authoritative source, the ELF include files in the binutils git
repository are kept up to date with the gABI changes, and I'm about to
commit a change there to reflect the new compression type.
