In BSD, the init(8) binary doesn't do much regarding startup - basically just executes /etc/rc; it's shell scripts all the way afterwards, nothing hardcoded. What exactly cannot be solved with init scripts? Also, keep in mind that FreeBSD init scripts (which actually come from NetBSD as rcng) are very different from the SysV mess Linux used to use - they handle dependencies, have a sane way of configuring way, they don't reimplement features which ceased being useful in the eighties (runlevels) etc. They are also quite fast. This means the pressure to migrate off to something else is much lower.
