And then upgrade all ports, while the services are running?

Just cause it doesn't fall into your 95% slice, doesn't make it messy. It's in 
fact cleaner then using compat6x, *because* compat6x doesn't fall into the 
category of potential causes when things don't work.
FYI: tinderbox is based on the pointyhat build cluster, which makes all 
the 'messy' packages for the FreeBSD package servers.
