Here is a list of most relevant forum topics where people ask for return of real detach of tabs -- as it was in pre Opera 9.5 or do it better. Opera "fixed" one potential (I didn't find any complains about this on Opera forums) UI problem with simply removal of this feature completely.

I believe 200+ replies and almost 12000 views should finally bring some attention of Opera developers.

With Safari 4 and Chrome have almost the same functionality working (tabs tearing) I think there will be more and more new treads asking the same for Opera.

Here also some cite from response called "Usability of tabbed browsing in Firefox" on 456 Berea St:

The usability studies were done at Google, using a special build of Firefox 1.5b1 that was configured to open targeted links in new tabs instead of in new Windows.
The testing revealed some things that caused problems for many users:

• Back button: When a new tab is created, it gets a blank session history, so you can’t use the back button to get back to the page that launched the tab.
  
• Closing tabs: Many did not see the close button, and instead used the contextual menu to close tabs. Some tried closing the entire browser window instead of just the tab.
  
• Stacking order of tabs: When closing a tab that was opened by a targeted link from another tab, the adjacent tab is made active instead of the tab containing the opening link.
  

The team experimented with some adjustments to the tabbed browsing in Firefox to find out if they would improve usability:

• Put close buttons on the tabs
  
• Change the closing order of tabs
  
• Implement an “Open links that would open new windows in tabs” preference
