Why isn't this ideal for a data center?

Many of us have very large data centers that are managed via DHCP 
exactly as you described without issues.

It makes life so much easier.  If I want to update an NTP server, I just 
update the config.  If I want to move a whole rack to another subnet, I 
just update the dhcp server config without making any changes to the 
clients, etc.

I use an include file for the hosts that have a static mapping that is 
generated programmatically.
