Difficult situation.  There's some really important information missing
from the changelog:

- Who cares?  Is there some real application which is hurting from
  the current situation?  If so, who, what, how and why.  If not, then
  why change anything?

- A description of the userspace API change impact.  How did the
  interface change?  What is the risk of this change causing damage to
  real applications?

If we can answer these questions then we're in a position to make the
pain-versus-gain tradeoff decision.
