For one thing, dh_installsystemd generates maintainer scripts for restarting services. Before version 13.11.6, it did not recognize the /usr location. If you were to backport such a package, bookworm's debhelper would not generate the relevant maintainer scripts. You can mitigate this by issuing "Build-Depends: debhelper (>= 13.11.6~)". Thus, you'll be using a backported debhelper (unless the backporter carelessly deletes this dependency).
If that would be the only reason to require a backported debhelper, then it would probably be better to make the file move conditional on the target distribution (from "dpkg-parsechangelog -S distribution") -- the intention of that is immediately readable, while a versioned build dependency needs to be explained or a backporter might want to carelessly delete it.
gcc does something similar, although that uses "lsb_release -cs", which is technically not entirely correct since it looks at the build system, not the current package, but for the purpose of backports is good enough and avoids corner cases like "stable-proposed-updates" not matching "bookworm" or "bookworm-backports".
