this statement is not fully true from a backview.
We need to ship the transitional icedove package for Stretch at all
times so a dependency on 'icedove' will end in the reverse dependency on
'thunderbird' and the extension will work. For Stretch+1 we need to proof
the xul-ext packages for depending on thunderbird then.

Christoph will check which reverse depends on icedove-dev we have.
