written to support only truncation in the future?  that seems silly too.
if someone ever tries to add any writability to this file system
(which seems very unlikely, since the disk format is not at all conducive
to modification on the fly), they can update this function to do the
right thing for whatever types of modification he adds.

calling UFS_* is an indication that the vnode might be any of the
UFS types, but in this code we know which one it is, so I think
it's clearer to use the real function directly, so that someone
reading the code can be sure of the vnode's type as well.
but as you say, it's a matter of opinion.
