I don't say anything about creating incompatible versions of the same filesystem. Configuring out nsec timestamps is no different than what we have today. Many filesystems do not support nsec timestamps anyways.
I just see this as one of many hundreds of "tiny" features that are added to Linux that could easily be made a config option when they are first added, but all just end up adding a tiny bit of bloat for people that don't need it.
