There's something to be said for having the full set. If you want to change grind and extraction levels, change basket and set the grind to get a good shot at the nominal dose. However, I don't think that the 15 grams (which is the lowest I know of) goes fine enough for really light coffees without help.
If I were designing baskets today, I'd specifiy them for grind fineness, from "Turkish," via "Italian" and "Cuban" to "Seattle." And no, these names are not a thing for grind levels, I just assigned them in the absence of any espresso grind level names.
The short summary of the video, at least for habitual oversimplifiers like me, is that the primary user variable for manipulating extraction yield is grind fineness, not dose or brew ratio.
