What do you mean by "chosen in preference to", the two are hardly mutually 
exclusive...? UFS2 is still FreeBSD's native filesystem, however FreeBSD 
also supports handling a range of other filesystems like ext2fs, NTFS, 
etc. - and now also XFS. If you happen to want/need ext3fs more than 
XFS then you can always add the required bits yourself and send patches, 
or pay someone to do it? Someone wanted XFS support, so someone went ahead 
and worked on it - not to the exclusion of any other filesystem that 
anyone else might want/need support for...

...and this has what to do with the fact that FreeBSD now supports XFS?

Then use ext2fs. Isn't the availability of multiple choices great?
