Very little. For all intents and purposes, negligible.

Security. bind is one of those programs that's been known to have a
large numbr of rmote root exploits in the past. If another turns up,
it's possible that a cracker could use it to break into your
(hypothetically) otherwise-secure web server. However, you can run bind
in a chroot, and do many other things to make it as secure as possible.
