I don't know about "just." It's a codec that supports both speech-focused and general-purpose encoding tools, and can mix and match those as is most appropriate for bitrate and content. It's really the same concept as Opus, with the same strengths.

The big difference is that it fits into the existing audio codec and MPEG ecosystems better. Not that Opus had any fundamental technical reasons why it couldn't, but there just weren't proponents pushing for it the same way and with the same resources.

Web/PC oriented technologies can innovate quickly and powerfully, but it's way harder to migrate from there to consumer electronics and living room than people imagine. Same reason why VP8/9 never had much traction outside of user generated content on the web. Premium content interoperable across all material endpoints requires a huge, huge effort from many, many stakeholders.
