I agree with everything you have said, except that Bacula will always have a
scheduler for those of us such as myself who do not need something
sophisticated. Though if you have an external scheduler like what you
describe, it is always possible to run Bacula without using its scheduler.
Over time, Bacula's scheduler will become a bit more intelligent (it is
currently due for a rewrite), but as you say, if you really have big
