The official policy is that file format changes must be backwards compatible not forwards compatible. In other words, the user will have to download the version KiCad where the change was made. If you make any changes to any of the file formats, you must increment the file format rev number. This will cause the appropriate exception to be raised which will warn the user the file version is newer than the file version supported by the version of KiCad they are using. Since this is all very new and has not been planned for the stable 5 release, I would most likely merge this into the master branch after the stable 5 branch is created.
