It has long ago been converted to a mount option instead of a
tunefs command in NetBSD. My FreeBSD systems are patched that
way since shortly after soft-updates was committed (long before
it became available in NetBSD, IIRC); I have not checked whether
they used the (very simple) patches I had posted at that time.

Controlling soft-updates during mount has many advantages (not
only if you decide to enable it on a root file-system that had
been created without it) and no disadvantages.
