Thanks for pushing the patch!
I thought it was not a candidate for backpatching because it's
a collation change.
Now, to have a problem with that change in a minor release,
a user would need to have an ICU collation with a rule containing
"[strength N]", where N<>3, even though it was ineffective (so
either the user did not notice or they did but kept it
nonetheless). Users who reported the problem hoped for a backpatch,
but we cannot say there is zero risk with that change in a minor
release. Personally I'm +0.
