With the current versioning, the option will be disabled for all existing files, even if users actually wanted to have it enabled. I'd just change it in the bundled startup.blend's, https://developer.blender.org/diffusion/B/browse/master/source/blender/blenloader/intern/versioning_defaults.c$185.

@Julian Eisel (Severin) Yes, I'm going to change the patch..I don't like do versioning for all files.. I'm waiting for an asnswer from Campebll before update the patch.

Don't patch files.

Still missing the change in startup.blend file. I think is better to do the change in a Linux machine than my Windows machine..it's just open it, disable the option and save it.

After talking with @Campbell Barton (campbellbarton), we don't need replace any blend file, because if you load factory settings the Normals are disabled, so I think we can commit this change.

The change in versioning_defaults.c does exactly that: It updates values read from the startup.blend's (each template can have its own startup.blend).
