It is simple to hit `o o' instead of `o'.  And it has the
advantage of reminding you of the fact that there are also
`o f' and `o b'.  `M-s o o' is no less "super useful" than
`M-s o'.

Those are horrible, IMO.  Instead of sacrificing `M-s b'
and `M-s f' you are sacrificing `M-s M-o'.  So you've
saved only one key.  And at the cost of introducing more
complexity.

And inconsistency, unless you also move `occur' to
`M-s M-o o'.  If you do that, then I'm in favor.

The point is to group all of the occur commands wrt
keys: have them use the same prefix.  Prefix `M-s M-o'
is at least as easy to use as prefix `M-s o'.
