As mentioned in our community call yesterday, once  is merged, `flang-new` will be ready to replace `f18`. I propose that it is deleted soon after so that we have only 1 driver to maintain.
As suggested by Peter Steinfeld, let's have a transition period of at least 2 weeks. I suggest that it's 2 weeks from when  is merged. Hopefully this will be sufficient for you to adjust your workflows. If not, we will extend this.
Please, if you either:
* use `flang` (the bash script ) in your workflows, or
* rely on `f18`s ability to call external compilers,
could you check whether  preservers everything that you need? With no testing upstream, it's been tricky to verify.
