Hi Hans Petter,

The issue here is that the onus is on the one changing a KPI to
support its consumers through the transition. This doesn't necessarily
mean doing all of the work. But the KPI changes, and techniques for
adapting to them, need to be communicated very well in advance of the
change arriving.

I appreciate that you have a patch for TCP in review now - but having
Adrian encounter a huge TCP performance regression is an unfortunate
way to discover this issue.
