Note: we are planning now a minor "interim" release to include #5833 and #5740
Ping @trexfeathers can we fit this in ?

Status : I think ..

• this basically works
• a fix for Cube printout should not compute lazy scalar coordinates #5743 is very desirable
• the new behaviour (coords print differently ) should not be considered a breaking change
• the broken test is a simple fix
• however, some more specific tests would be a good thing

@fnattino if it's ok with you, I'm going to take this + add a couple of commits to fix + extend the testing slightly.
Then we can bank it.
