I've made a visual proposal for what I now call path-guided raster
(maybe I should add "freehand" somewhere in there as well).

Description and advantages:

Possible effects:

As you can see from the examples, the vector back-end has 3
major benefits:
- smoothing
- total path length
- path angle

I won't repeat the advantage of an easy map-to-stroke length
feature... 

The angle effect could be useful for guided shading (the base
brush would be a series of dots, they get rotated along the
path), but also be a very quick way of applying brushes to
a certain angle: increase the spacing to avoid multiple instances, 
draw a short line in one direction, and you get a single stroke of 
pepper/flowers/letters/whatever in the exact direction you want.
Neat!

Also, because the output is raster, you can apply whatever
effects you need with it. Add some size jitter for example,
and you can emulate a natural-ish ink stroke.
