JPEG-XS is an almost direct successor to VC-2. They use the same techniques and if you read JPEG-XS's whitepaper they explicitly cite VC-2 as an inspiration and a target to surpass. JPEG-XS is an improvement, there is not doubt about that, but unfortunately they decided to patent it for all uses. In both cases, the publicly available software implementations are very few, CPU-based, and the ones that aren't are implemented in hardware inside business AV solutions.
