Also, [LWG4147](https://cplusplus.github.io/LWG/issue4147) (#118361) seems to be Nothing To Do, but IIUC we should treat it implemented together with `inplace_vector`.

[LWG4396](https://cplusplus.github.io/LWG/issue4396) (#171373) doesn't seem being implemented. I'm personally fine to have it implemented in another PR because it touches a concentrated mechanism about "statically sized" ranges. Would you mind to implement it together?
