I'm not the code owner, this is more a vote. However, we have been struggling with the synchronization scope for few years and two backends now. Neither metadata nor intrinsics work well and this is the only comprehensive solution I have seen so far. The issue first arose with OpenCL 2.0 implementation and it looks like lack of support is going to impact us more and more. It also looks like not only we need this, there are also other parties interested. All of that makes me think IR extension is well justified.
