I don't think that a revert is appropriate.

But perhaps just a single printk() or something if the user does *not*
specify the version explicitly? Just saying something like

  We used to default to 1.0, we now default to 3.0, if you want old
defaults, use "vers=1.0"

Oh, looking at that version parsing code, I think we also need to fix
that legacy "ver=1" thing (ver without the 's') which now silently
ignores "ver=1" as being the "default", even though it's not.

I do *not* believe that "default to version 1" is acceptable.
