the absence of the await in P0114 is a likely source of many maintenance nightmares

We have no idea how P0114 would play out because no one took the time to implement it. We only heard from the opposing counsel (Gor), and he only offered opinions. I spearheaded an effort to implement P0114 in clang and we made some progress, including necessary modifications to the original paper to make things smooth and also address some issues raised by other stakeholders. But the talent I was working with did not have enough time available to complete the project. One of the modifications was an "opt-in" model of resumable expressions, to avoid the problem where code unsuspectingly becomes suspended at a place that should not suspend (for example, while holding a mutex).

High quality engineers familiar with Clang/LLVM are mostly already working on projects, and also employed by large corporations. The mere existence of Coroutines TS, plus the assumption of correctness conferred by the author's employer, discourages significant investment in alternate implementations.

Thanks
