I know they have special meaning. At the other hand, if we allow them, we will allow to store them on a filesystem. Wouldn't it be nice ? This is useful at least for SquashFS image preparation.
I guess for similar reasons we have support e. g. for device nodes (/dev) with their major/minor numbers. They are also ignored by Cygwin, and just stored on the filesystem (or do i miss something ?).
