I've been working with systems that support extent writing for many years (JFS2 mainly in the *nix world). While the overall performance is increased on read/write and seek times (especially in RAID-5 or any other striped RAID for that matter). For a desktop support for extents is just another over kill.
All were seeing is the transition of technologies which have been in the commerical space coming home to desktop users. SMB/SME will benifit from such transitions but with improvement comes increased complexity and therefore risk... If you running a desktop ext3 and even ext2 is most cases works fine.
