I hope that mergers understand the changes they merge, and understand if
they are still necessary or not (for Ubuntu). If not, that confirms
that there's an issue with documentation of the changes.
But I agree with you that the Ubuntu Developer is not in the best
position to judge whether a change is applicable or not to Debian.
Something you could do without giving the impression that you are giving
orders to the Debian maintainer, is to clearly mark Ubuntu-specific
changes, when they are only useful for Ubuntu. A simplistic example
* Replace iceweasel with firefox in Depends.
Ubuntu-only: firefox is renamed iceweasel in Debian.

Sure. But that's a different issue: Ubuntu developers are never going to
open a bug in the BTS for every minor change they make to a Debian
package. I agree that bugs should be preferred, but that's not a reason
not to improve the way you communicate through debian/changelog.
