It would be nice to know if, for example, the root partition (or any other partition) was mounted read-only ('ro'), if for example the filesystem had errors and thus was unable to come up properly. This is primarily for problem detection. It may be exposed through Hyperic library: http://www.hyperic.com/support/docs/sigar/org/hyperic/sigar/FileSystem.html#getOptions() However, the mount options may contain lots of other things not critical. Perhaps a simple 'read only' flag would make sense rather than showing all the mount options. I'm not sure what operating systems other than Linux what might be indicators.
I have added mount options as available trait, so comparing this to previous value should warn you (in case of read-only). And this is a bit more general property for other users also, as those options should not change on their own.
