At times it can be well worth while calling a shove when you think you have only 10% hand equity. If the pot is already large it can give you a decent overlay, enough to make it worthwhile calling - be a little careful with what really is a coin-flip and what is a break-even spot.
Like most things in poker the point calling allin makes sense depends on quite a few factors. Your overall 'edge' in the tournament will come into play but even then the 'edge' you should apply will vary with many factors like how well your stack plays if you fold, how much your chances improve if you call and win.
Personally I don't give up much edge in most situations, if you do you also have to remember that anything you give away may often get compounded later, you are giving this 'edge' to another player ie, an opponent. If you fail to call a 5bb shove from the button shoving a wide range then in the next orbit you can face a 6.5bb shove and if you fail to call here this player has now got a stack with some decent fold-equity
I think it is better to view this issue from the more common small stacked situations than the almost hypothetical 200bb shoves, calling or folding against these won't make much difference to your overall roi as it hardly ever happens.
Everything requires some judgement and thought really.
