I am stating why it cannot be a two way avenue, I am not telling people to use this feature as it is still under review.
The adopt-info feature has been discussed on the forum (Extracting existing data from projects to feed into snap.yaml), the doc is not merged as it mentions features not yet available for consumption. However, the available features were announce https://github.com/snapcore/snapcraft/releases/tag/2.38
We want the full story before the documentation reaches general availability.
