I agree with you in your opinion that it should be strict by default.
But jail have features other models don't. For example the unique IP
address of the jail. If you want that feature, you should use jail.
But if you use jail, there are other restrictions which in some cases
means you cannot use it.
So if you need one feature of jail, but blocked by another one,
you are in trouble. This is the case with ntpd, this is my case with
X, and I am sure that there are others out there with similar

Sure, a strength of rsbac is its rich offer of different security
modules. The problem that these models are not orthogonal.
You know, the good old unix approach: we have tools which do
only one thing, but do it well, and we have a common approach
to make these tools work together well.
