For me, not at all. My coloring tool of choice is the pencil, so building up with little strokes makes all the sense to me. The roadblock with pencils is the inability to blend colors on the palette and I find doing it with layers of differently colored pencil results in stress-induced hair removal. Likewise, mashing together large brushstrokes as in traditional painting doesn't make any sense to me. Pencil-like strokes with paint was the natural solution.
It's just one of those things where what seems tedious to one artist is the zen activity of another.
