Some enrichments should offer a preview, where they simulate the effect of the enrichment against the first 100 columns and display the results without making any changes.
This could work using database transactions that get rolled back rather than committed, or it could use some custom mechanism for each enrichment.
Not sure the best way to abstract this - maybe it's to let each enrichment that offers a preview also bundle a preview template that gets included in the page when you click the "Preview" submit button (which only shows if the enrichment supports previews).
