I will let Jon Gjengset answer that, since it is his patch (cc'ed on this message).
See discussion at
  https://sourceforge.net/p/gnuplot/patches/633/

I had the same initial reaction as you, that only the "i" key was necessary,
since you could get back the full set of plots with a replot or "e" key.
The counterexample is a multiplot.   You cannot replot an
individual panel of the multiplot, but the "v/V" keys do work to 
display or hide the full set of plots in that panel.

It is still true that  "V" = "v" + "i"  and therefore so far as I can see
only one of the keys "v" or "V" is needed.

I agree that some command line interface is possible.
That was the reason for implementing this as a terminal entry point
rather than just handling the hotkey event inside the each terminal
driver without notifying the core code.

The issues of multiple windows or multiplots in a single window
complicate this.  If you read through the discussion attached to the
patch, you'll see that we discussed adding additional parameters to
the term->modify_plots() interface to handle multiple plots or windows.
But I thought people would like to try it out in the current form
before discussing possible extensions.
