I imagine that deep-immutability could be useful to folks. For example, I could get a read-cap to a deep-immutable dir from someone, inspect it (manually or with a script) to make sure that all the files in it have some property, and then pass that cap on to someone else and know that whenever they use the cap, any files that they get will have that property.
Note that this assumes that either the Tahoe-LAFS gateway used by the recipient to whom I give the cap has the "ignore any mutable children" feature, or when I inspect the directory structure I have to make sure there aren't any mutable children in there. It does not assume that the person who gave me the cap in the first place has a Tahoe-LAFS gateway that has the "refuse to insert mutable children" feature.
