I am not an expert, but I think this could be improved if the smartphone operating systems had better security models.

For example, an application needs "access to your disk storage", because it needs e.g. to save photos. Okay, let's give it access to its own directory. Or maybe to a subdirectory of "my pictures". But it doesn't need the access to the entire disk, right? Yet in Android, it is all or nothing.

Perhaps with better system, we wouldn't have to ban installing game mods, only to make sure that those game mods do not have unreasonable access rights. Or maybe the banking operation could state "I can only be installed when no other app has an access to my private data" or something like that.
