You are right.
But this problem only occurs, if you were logged in and if you somehow 
manage to keep the BE there without the re-login popup coming up. I think 
this is a very seldom case. (Is that possible at all?)
The most common case should be, that a user opens his browser window again 
after having closed it and then the browser opens the last URLs again. In 
that case the browser will load typo3/backend.php. And there you won't get 
any frames, because the whole site (backend.php) will be redirected 
immediately.

Taking into account that without your patch there always is that ugly error 
message I think integrating your solution really is the better choice and 
therefore is the way to go.
