As Dmitry says, -dev packages should not have Built-Using headers at

"Some binary packages incorporate parts of other packages when built
but do not have to depend on those packages. Examples include linking
with static libraries or incorporating source code from another
package during the build. In this case, the source packages of those
other packages are a required part of the complete source (the binary
package is not reproducible without them).

A Built-Using field must list the corresponding source package for any
such binary package incorporated during the build..."

Lots of -dev packages _do_ have Built-Using though, we should try to
kill them off...

If there are binary packages with out of date Built-Using, yes,
rebuilding will fix.

As above, not really the right place for it?
