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".
