Speaking from a jurisdiction that has a weird attitude towards liability
disclaimer, may I add that unlike many other copyright-related aspects,
the liability disclaimer is by definition jurisdiction-dependent, and
therefore an imperfect tool that cannot be fine tuned for any given
situation without such effort being largely useless in many other

I don't see "better liability disclaimer" a good proxy to assess the
worthiness of a new license in terms of non-proliferation.
