The disadvantage of this approach is obvious as soon as thickness is increased.

That’s true but the function stencil-whiteout-outline (from scm/stencil.scm) takes not only a thickness argument but also three other arguments called color, angle-increments, radial-increments.

• color is used to make f. e. a “redout” instead of “whiteout”, useful for colored backgrounds. • angle-increments (default 16) determines at which angles (default: multiples of 360°/16=22.5°) the white symbol should be printed. • radial-increments (default 1) determines the number of copies between the original an “thickness away”.

Increasing radial-increments or angle-increments (or both, depending on the shape used) could reduce such problems. But I haven’t found a way how to do that as a user (\markup \override #'(angle-increments … seems not to be the right way). And of course depending on the shape one might need very many copies.
