My opinion on this remains the same as it was when I wrote 
["Thoughts on Backward Compatibility"][1]; to wit:

* Even without an edition bump, small-scale breaking changes with 
easy migration paths aren't a big deal.
* Even with an edition bump, large-scale breaking changes that 
make migration difficult should probably be avoided.

In other words: the presence of editions in a language does not 
really make a difference w.r.t. which kinds of breaking changes 
are feasible to introduce.

Since the stated purpose of editions is to make it easier to 
introduce breaking changes, I believe that this flaw renders the 
entire proposal unfit for purpose.
