Yes, it should.

In fact we tried to get Scott into a discussion about a common API
definition for this and other similar smaller interfaces for usage in
daemons. Alas, Scott's only reply was that our approach was "too
simple", and nothing more specific.

Well, you should know the longer history of this before making smart
comments like this one.

Yupp. We tried this, and got basically told to bugger off, and so we
did. Scott said pretty explicitly that he had no interest in cooperation
on interfaces like this one, and that's that.

If the opinions on cooperation on APIs on Canonical's side changed since
then I am all ears. In fact I offered to come to UDS, if you guys want
me to, and maybe we can discuss that there.
