Since there is a comment and new version will be anticipated I also
would like to propose to change INTER to IFACE because latter more
particular. Darren?

There is a specifier to print struct resource, please use it instead.
%pR IIRC.

Same for all similar cases below.

Yes, I had the same thought, but wasn't going to request the change just for
this. Andriy did point out the pointer format below previously however. Please
do correct that - updating INTER to IFACE would be a welcome improvement as
well.
