Well now you've filled in another bit of jigsaw, I find in the 
archives for the old dhcp-server list this message from 2006 :
http://marc.info/?l=dhcp-server&m=114059935806364&w=2
where I give the list as :

no ip forward-protocol udp tftp
no ip forward-protocol udp nameserver
no ip forward-protocol udp domain
no ip forward-protocol udp time
no ip forward-protocol udp netbios-ns
no ip forward-protocol udp netbios-dgm
no ip forward-protocol udp tacacs

I don't claim originality - I was only passing on what someone else 
had posted earlier (much earlier)

It's a really nice feature that isn't it - enable one little service 
and it automatically 'helps' you with a bucketful of others that you 
would probably never (or rarely) want to forward.
