Comment 1 for bug 1534684

It would be misleading. The fillWidth means that the column will occupy the remaining space even if the other columns have no content. The columns are prepared and should be like that. Usually the last column is expected to fill the width. This has been discussed with UX, and the APL works according to that.

Beside, this would cause relay outing, which also may have performance issues, may cause models to be re-loaded from the web, etc. Of course this depends on the implementation, but it will definitely cause re-rendering for your [ArticlePage].
