My thought process is as follows:
Field 4 is for mount options. This is just the same as providing
options to the 'mount' command issued at the command line.
And it is ok to use the 'mount' command without options.
Regarding omitting 'sw', I'm not seeing any problem.
This might be a good starting point to investigate whether
anything uses it:
