In describing the fix for #833, Zooko said:

#833 also adds some very nice forward-compatibility features, so that when future versions of Tahoe-LAFS start uploading new kinds of capabilities, people using Tahoe-LAFS v1.6 will get a reasonable
indicator showing that there is something here that is immutable, but is from the future so you can't actually see it, instead of getting a traceback or some sort of behavior that violates the deep-
immutability property.

However, #833 didn't actually change directory listings to show unknown caps as immutable (?-IMM) or read-only (?-RO). I have a patch to do that.

The ternary operator isn't available in Python 2.4 so we can't use it yet:

+        d.addCallback(_check_directory_html, "-IMM" if immutable else "-RO")
