This project conversion affects only projects, that were edited after #97707 (v4.4-dev4) and provides an easy way to upgrade these projects.
It seems reasonable to assume, that at that time of the next stable Godot-release all affected projects have been converted.

For projects, that haven't been converted, we can provide an upgrade-strategy, that that consists of opening the project once with v4.4-dev5.
