I have had softupdates turned on for all of my mount points for over
a year.
For /, the only issue is that if you have too small a root parition a
'make installworld' may run the filesystem out of space faster then
softupdates can free the blocks. My root partition is always 128M
for that reason (and also so I can throw a few kernel.debug images in
there).
My recommendation is to turn softupdates on for everything you have,
and for us to make it a newfs default as well. At least in -stable.
