Only at the time of loading a package and only a package or two in the
following do I use. After loading the packages, they won't change the
rng any more.
But calling (random t) every time a function is called just gets in the
way, that means I am no longer getting a uniform distribution from the
RNG. Also (random t) is much more predictable.

That should leave for the user to do. Common Lisp also does no seeding
at start up.
