I hope this task can be prioritised. It would help acceptance of the still under-used "excerpt" feature, particularly in featured articles. So far editors of featured articles don't like excerpts to be included as they wouldn't get notified of changes to the transcluded article unless they manually put it on their watchlist. Excerpts are an amazing tool and I see a big role for them for certain types of articles, for example those in the climate change field but also environmental pollution, many sciences and so forth. Wherever data is changing over time and would have to be manually updated in several articles, an excerpt saves heaps of time and improves overall quality of several articles at once. See also discussion here. See for example WikiProject Climate Change here.
