Compared to the use of a prefix, there is an important difference: the
prefix tells isearch that the next command is a movement command, so it
can be used with *any* command (and can lead to surprises if the command
is not a movement command), whereas in the absence of a prefix, isearch
would need to know which commands are "movement commands", and this
knowledge would always tend to be partial, so it will fail with
some commands.

Depends significantly on your usage pattern.  I know such a change to
the default behavior would cause screams and never ending arguments.
So we'd fist have to see this change in action for a while to
demonstrate that the benefit is worth the cost of transitioning.
