While that sounds nice - the versions in this change is the ones we have discussed in the RFC and the higher we bump versions the more people we are going to lock out - so I think we'll keep 7.1 for now and if we encounter specific breakages / bugs in that version we might update the document and suggest people use the latest 7.x version instead.

Here is the rough plan I am thinking right now and I will post in the forums soon:

- Announcement in the forums that this is happening today or tomorrow.
- Let's allow a week for buildbot owners to upgrade before we merge this commit. Maybe merge it end of this week or maybe beginning of next.
- The soft error will live in `main` until we branch for LLVM 15.x
- When that has been branched - we will convert it to a hard error in `main` and up the CXX_VERSION to 17.
- LLVM 16.x will require the new toolchain and you will be allowed to use C++17 features.
