Update: This was moved to Meditations

This should really be in Meditations, I really think that alot of these types of decisions are (or should be) based on the target audience. When I release scripts to members of my team, I typically leave all warnings on. It helps them debug problems they might run into and lets them give me a more detailed bug report.

For release to the general public at large, again consider what level the target audience is going to be and leave what you feel appropriate in. This doesn't mean there won't be exceptions in your audience, but you want to do the Right Thing for the bulk of your users.

After doing this for a while you will get a feeling of what works for you.

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!
