While copying a message I made in another thread all the restored functionality to these apps proves is that they have a latent memory corruption bug that the developer hasn't, yet needs or should resolve when the only way to get these apps working is to disable the hardening via the toggle.
The project added the feature to ensure that people could have the informed option to disable it to maintain functionality or choose to use alternatives knowing what causes the problem.
At the end of the day GrapheneOS is for everyone™ ;)
