To fully evaluate this idea I'd like some additional information. What
in your opinion justifies the full backport of unattended-upgrades?
Please provide some examples of bugs that would be fixed by SRU'ing
version 1.1ubuntu1 of unattended-upgrades.

Speaking of the autopkgtests I didn't think the test coverage of
unattended-upgrades was that great. Has this improved in version
1.1ubuntu1? What new tests have been added?

Fixing additional errors on top of 1.1ubuntu1 makes sense to me.

This also sounds reasonable.

Thanks for bringing this up!
