Spend, spend, spend. Why not save a few bindings for a future rainy day? ;-)

The argument that we should do this because most browsers do it is a good
one, if true (I take your word for it).

But the argument that S-SPC is currently useless because it is unbound is
not a reason to bind it for this purpose.

Are new users really finding their habits so terribly violated by Emacs that
we need to make changes such as this? PageUp and PageDown are also used in
most browsers, and Emacs supports them. How much is enough?

Go ahead, if you really think it's helpful. If a better use for S-SPC comes
up, I'll argue to change it then. ;-)
