This is really a challenging question...
I cannot say Yes or No clearly, partly because I sometimes enjoy attractive new productions of classics as well as so-called original versions.
Considering theatre plays, you can also see lots of 're-interpretation' Greek dramas and Shakespeares in the context of Feminism or post-colonialism nowadays. The problem in the discussion of ballets would be, however, that they do not have absolute original, such as written texts.
That's why I always find it difficult to know; how 'original' this Swan Lake is.
As far as Romantic ballets go, I would imagine how difficult it would be to make a contemporary version of, for instance, Giselle, as the concept of these ballets can be clear in the historical context of Romanticism, the idea not close to us living in a contemporary society. In that sense, Romantic ballets without Romanticism sound pointless.
Interpretation by the audience, however, cannot help being updated.
