No, actually it's not expected to do that.

The current behaviour allows users to override permissions on
directories without having to worry about them again after upgrades.

The side effect, of course, is that wrong permissions are not
automatically "fixed" by dpkg, because dpkg does not know whether they
are different because they were wrong, or because you wanted them to
be different.

The current dpkg behaviour assumes the user knows what he/she is doing.
I don't think dpkg maintainers will want to change it, but feel free to ask.
