Depending on what you mean by "ok".
It may be "safe" in the sense that bundles that allege to be
configuration cannot execute rm -rf /, and even "safe" in the sense
that they can't begin executing an infinite loop.
It is not "safe" in the sense that the space of possible
configurations is kept to the minimum necessary; it is also not "safe"
in the sense that the correspondence between configuration text and
resulting program behavior is kept comprehensible.
It is these latter properties that are important in the long run
