Just to be consistent and safe, really. And to avoid unpleasant
surprises ("hey, why is my system so slow, I had the softdep flag
enabled in all my FFS filesystems").

Correct. Which is why the softdep flag is still written in the superblock
if you mount it with -o softdep, and cleared when it is unmounted. So,
if there should be a crash, fsck will still see the flag and act
accordingly.
