Yes. Philipp, were you aware that the file's versioned contents
contains more information about the specialness? If we also made the
prop val contain such information, we'd have to figure out what to do
when it disagrees with the file contents :-). Much better to keep the
prop val as a boolean flag, and let the contents remain the single
source of information about the specialness.
