As the administrator, I know when the contents of the file /etc/exports will be consistent on disk, and I indicate that to the daemon by sending it a signal. If daemons are capable of detecting file writes or spontaneously re-reading, they run the risk that either they'll see an inconsistency during the file writing process from the editor (mid-memory-chunk, say), or that they'll hit a copy which I've saved but not yet finished editing. I'm all for making restarting daemons easier -- you can imagine a daemonctl or something that speaks "restart" for a bunch of daemons, but automagic can sometimes hurt you more than it helps you.
