the attribute indicating the auto-smoothness can be entirely ignored by renderers
But if you animate an autosmooth point (or a regular cubic bezier curve point) the curve around it changes; the question is if the curve around it maintains its smoothness. With normal points, it doesn't, and quickly becomes a 'nasty' curve, with autosmooth points it does for the 4 curve segments surrounding the point, and with spiro points it does for all the curve segments until a corner or tangent point.
This is especially important for glyph shape interpolation (designing a set of thin, regular, bold weights, etc) and also useful in animation ("shape tweening" I think its called.)
