Motivation for this change

Merge policy

As a rule of thumb:

• PRs with several commits that make sense individually and that
  all compile are preferentially merged into master.
• PRs with disorganized commits are very likely to be squash-rebased.

Reminder to reviewers

• Read this Checklist
• Put a milestone if possible
• Check labels

[IshiguroYoshihiro]

It looks good for me.
Thank you.

@proux01 is that ok to use the _tmp for a two stage deprecation?

[proux01]

Yes, that's what we usually do.
