I have an impression that markup generated by children often added using %s to some other construct.

It may interfere with export filters. I do not expect negative effect from a comment added at the end of line. Optimizing pass may be performed prior to user filters. As another approach text properties may be used as a communication channel unless they are stripped by ox.
