Ah, see earlier discussion.  We at least want to be able to choose
between strong and non-strong dedication.  And having used this command
I think non-strong dedication is a much better default, since it allows
users to explicitly run C-x b to change buffers without having to switch
off dedication.

It's not common at the moment, but I expect some users will use this
command quite frequently.  Also the C-x w prefix is pretty empty at the
moment, so it's not as if it's competing with anything.
