Thanks.  Last time we discussed about this, the conclusion was that Bison should implement this now.  Should we rather backtrack and postpone until the revision is published?  I have published 3.8, but not announced it yet, so it probably doesn't spread too fast.  I could revert that, and publish 3.8.1 very soon.

I don't see why this time they would agree not to change anything.  I believe we already clearly stated that this is a breaking change.
