So the solution is not simple and probably not clean either because the file system does not tell you if it is case sensitive and because we have multiple filesystems within a single scan possibilities. The most common change is probably running on windows and scanning an archive. The directory separators are different and the case sensitivity may be.
So..... What we could do is create a static map of Filesystem class to additional information (currently only the case sensitivity). When we first encounter the file system it will not be in the map and we do the standard check to figure out if it is case sensitive and then store that in the map. Subsequent checks for the file system will discover the earlier test result and not have to make the check again. Does this make sense?
