With the success of prop=redirects, in Gerrit change 155592[1] I added new prop modules prop=linkshere, prop=fileusage, and prop=transcludedin, which are roughly equivalent to list=backlinks, list=imageusage, and list=embeddedin but can work on a list of titles (including titles from a generator).
They should be deployed to WMF wikis with 1.25wmf1 (unless we call it 1.24wmf23 after all), see https://www.mediawiki.org/wiki/MediaWiki_1.25/Roadmap for the schedule.
I'm considering deprecating list=backlinks, list=imageusage, and list=embeddedin at some point in favor of these new prop modules. Opinions on this are welcome.
