It's always been there, at least for terminal that support dashed lines.
The terminal option is {dashed|solid}.  In fact the postscript terminal
defaults to dashed lines, and has done so since the beginning. The other
terminals default to solid lines.  The appearance of the dash patterns
can be further adjusted using the terminal option dashlength ("dl" for
short).  The dash/solid property is separate from the use of color or
grayscale.
