Did `TaskGroup.spawn` change to `TaskGroup.async` from this last review which still haven't officially concluded? ↓

> Hello, Swift community. The second review of [SE-0304: Structured Concurrency](https://github.com/apple/swift-evolution/blob/main/proposals/0304-structured-concurrency.md)begins now and runs through April 16th, 2021. The [first review](https://forums.swift.org/t/se-0304-structured-concurrency/) received largely positive comment, but led to a number of revisions, particularly regarding naming of methods. You can find a diff for the revision [here](https://github.com/apple/swift-evolution/compare/9b5e0cbd552b4c8b570aedcb94c0cb72b9f591b0..309f60fcb4f0ad4e1412adb1d0ee9ccaad0419c1#diff-6e3f26a7c1e2c41a13bcf34ef4c7d84625339b2898702f5e0bed0d6e05f1a778). This review is part of the large [concurrency feature](https://forums.swift.org/t/swift-concurrency-roadmap/41611), which we are reviewing in several parts. While we've tried to make it independent of other concurrency proposals that have not yet been reviewed, it…

I like `spawn` keyword that align with `TaskGroup.spawn` and explicitly describes that spawn execution process which runs in parallel.  
The word `async` doesn't have any hints about this execution flow.  
With language specs accepted previously, `async` is serial execution model with `await`.
