I believe that's the same in FreeBSD as well. I also think it's a solved problem in the Linux world - OpenSuse Tumbleweed sometimes rebuilds every package because they've changed libc. Apart from watching 2000+ packages get updated, there's really no impact when this happens. To solve this, the updater could create a new boot environment[0], install everything in that boot environment using as many passes as required, then reboot into that environment. OpenSuse already does a similar thing[1], though I don't know how well it works.
