Should I disable feeds?

Hi there,

I'm just wrapping up a client's site - and I wanted to ask your advise on feeds.

My client is not using the feed feature of WordPress, they have no subscribe link,
and will likely never write posts, the site is comprised of several pages and if anything they will just make copy edits to those.

I had a bad experience once, where my site's feed got hacked.
Since they are not using it, do you think I should disable the feeds to their site?
