yet, planetary chaos early on - in the form of a literal 'collision of worlds' - contributed directly to Earth becoming habitable.

Over the long run, the unstable systems must end with either the destruction or expulsion of the planets, or a degree of stability being attained.

Agreed. So the habitability question is chaotically sensitive to initial conditions.

something I'l have to look into someday (along with a giant tottering pile of other projects)

hunting through various star catalogs to see if the planetary systems of the younger stars are more chaotic (chance of collision higher) than the planetary systems of the older stars, arguing for planet orbits becoming more stable over time. made an effort at this in the Alternative Earths project, but was hampered by bad star ID's and dubious stellar ages...
