I expect it would be best to have it default 'off' for /, because the
user can get into strange-seeming failures when installing a new kernel.
I do like the idea of it being on for most other filesystems.

I don't have much of an opinion as to whether it should also default
to off for other "small" file systems.

Given the benefits, it might even be reasonable for 4.5.  Certainly it
would be nice to do with 5.0.

[whatever happened to softupdates becoming a mount-option, instead of
something set in the partition via 'tunefs'? ]
