Well if you make DuckDuckGo your standard search engine you only get search term suggestion without actually executing the search if you don't choose one of the terms or hit enter with a non-url in the bar - not sure if there is anything negative about this feature

I already have it set to not show any search suggestions since if I wanted that I would use the search box. I want it to not send the data anywhere if I hit enter (by accident, because I pasted what I thought was going to be a domain name but turned out to be something else) and it isn't a possible domain name or ip address. Not super high impact (accidently pasting a password I assume would generate a DNS lookup anyway) but it fells like a completely gratutious invasion of privacy when I have already indicated in multiple ways that I do not want to search from the address bar.
