You've found the thing as far as I can tell.

The 'best-solution-at-the-time' is the left:/right: tags you have
found, which was the original way these things were indicated and are
highly dependant on the direction the way faces any change of that
and they're messed up.

The boundary relation seems to be a much better method of grouping the
related ways. As for showing the names place=suburb,name=* somewhere
inside the boundary seems to be the accepted way of doing things.
(Automagically rendering the names in the centre of the area would be a
nice idea though :)

Boundary levels of 4,6,8 and 10 all render on both Mapnick and OSM
although the higher numbers (as of the last month) only show up at
zoom levels of 15 or higher. 

Check around Salisbury in S.A for examples of their use, I have
examples of suburb boundaries, post code boundaries and council
boundaries in that area.
