This is a real shame. One of the selling points of Linux is that you 
*don't* need to reboot for every little upgrade (unlike a certain other 
OS I shan't name).

Yes, please. Though maybe with prompting; we shouldn't go restarting 
possibly-critical services without good warning.

As David said, for dhcpd, 'service restart dhcpd' should be fine. For 
dhclient I would question why /any/ restart is needed. If your dhcp 
connection is currently established, is dhclient even running? And even 
if it is, what benefit do you get cycling the interface /now/, if the 
new dhclient takes over whenever the interface cycles anyway?
