I will speak to what I know, which is the reiser4 part of the story.  There 
will be no repacker/resizer or any other modules for the fs until it gets 
merged into the kernel.  During the process of getting reiser4 into mainline 
many things about the implementation are changing so it is probably 
impossible to write the compression or encryption modules until it gets 
merged.

I don't consider it a lacking feature, just a nice checkbox to be able to 
check.  If we get transparent compression in the filesystems (that you can 
toggle on and off) then that will be great news to marketers.  It also could 
be good news to embedded people if the compression isn't too processor 
intensive.
