Bell Housing Plugs

So, I've only ever seen these on an existing Blazer once. Are they important to keep dirt and mud out of the bell housing?

I had them on mine before I switched to a manual transmission. I can't imagine it could be a problem if they aren't there. At least if water gets in, it can get back out again without them.
