Aren't they simulating hardfork detection though? and this feature should be available on 2.9.0 which should get released in the upcoming days.
The version 2.9 release notes say it will have automatic fork detection, but I don't know exactly when installers will be released. There's only two weeks to go before August 1, and unexpected bugs could delay the release schedule.

multiple branches
