Do we need this SEO setting?: "Append topic ID to title and description meta tags"

Greetings Lithosphere! We have the following SEO setting checked by default: "append topic ID to title and description meta tags". It appends a string of numbers to the topic title, which means that in Google Results, there is a number in every title. We'd prefer to remove the number, as it's not aesthetically pleasing.

I understand the underlying SEO reason for this of avoiding duplicate content. However, none of our posts should have the exact same content. If they do, someone has cross-posted and our moderators should address it.

Can we safely turn off this setting and stop appending the numbers, without hurting SEO? Any other considerations?

Cheers,

Alan
