I disagree, when reopening the entire browser it is a perfectly legitimate use case to go back exactly where you were. Opera has long had the feature to tell the browser to automatically reload a page every X seconds, Minutes, or hours. So if you're use case is you need to constantly need updates on the current thing being hosted, Opera already does what you want.
Now, perhaps there is a misunderstanding of what the summary is talking about in terms of reopening a tab. This is only occurs when you reopen a group of saved tabs (generally from the last time you closed it). This does not occur if you simply type an address, click a bookmark, or any other "normal" method of opening a link.
