Exactly - in the Polish Wikipedia it is done very frequently. And also in Russian, Ukrainian, Hebrew and possibly other languages.
Look at the little green boxes under the edit summary field. It's stuff like "orthography", "fixing links", "wikification", "adding templtes", "adding infobox", etc.
You can frequently see these canned responses actually used in Recent Changes. It's not too hard to analyze all the edit summaries by querying a database dump a bit to find the precise numbers.
I have no idea why it hasn't been used in English, but of course, it doesn't mean that it shouldn't use them. There are a lot of good tools in non-English Wikipedias that aren't used in English. It's the English Wikipedians' loss. The best ones should be properly productized.
