tldr; I don't object.
As I mentioned down-thread, we had no data about breakage, now we have
a full openSUSE:Factory build and Andreas and Florian have addressed
all the issues that were seen. With this data in hand I don't object
to a single cycle removal.
At the end of the day I feel that it's a sufficiently simple change
that single cycle removal is fine. Any more and we're probably wasting
our own community resources tracking and making sure we actually
deprecate the interface and don't forget (see Zach Weinberg's
excellent paper: "A Maintenance Programmer’s View of GCC" talking
about incomplete transitions).
