Interesting, I didn't know that these existed. What they are used for?
What is the difference to FileDirectory? HTTPSocket, KomServer and
friends doesn't seem to use them.

Another thing is that Seaside is nowadays regularly ported to other
dialects (and potentially to more). Using Squeak specific code makes
this more difficult.
