This is not a revelation. We've known this for, literally, years. It's
been part of every previous init script discussion we've had on
debian-devel. However, many of those features can be made optional or be
implemented another way, not to mention that the FreeBSD kernel is not
static either and can adapt and adopt new features itself.
Porting any more modern, event-driven, session-aware init system to
FreeBSD is going to require actual work. I don't think anyone is under
any illusions to the contrary.
