It is broken by design because it contradicts with some general principles, such as "single responsibility", "share nothing", which leads to "divide et impera" and other "nice things".

Unix philosophy, according to which a system is a set of lose-coupled tools, each of which, at least in theory, is supposed to do just one thing, but do it well, and to follow certain conventions, such as using text streams as input and output, which allows them to be hooked together into pipelines, is a really great one. To sacrifice it just for very contradictional arguments of people, who, perhaps, not fully understand it or its consequences for a complex system's design, is, at least, shortsighted decision. (look what a wonder is Plan9, at least from the system design perspective and "less is more" principle).

As for so-called "problems", BSD people would tell you that most of these "problems" are mere creations of distracted minds.)

Introducing various daemons and ctls merely adds unnecessary complexity compared with the uniformity of "just shell scripts" and a very simple set of conventions. At least everything works fine with FreeBSD and its huge ports collection.
