Hey Nicolas,
Sorry for the multi-months pause, I was working on other stuff recently.
Thank you again for the insights! I’m not sure anyone besides you has ever used this property, but now we know
about at least one use-case. 
That’s why I slightly changed the proposal: the property would only be deprecated
as soon as the resource to object migration happens, and it would be kept at least for an additional major release
cycle.
I hope that the proposal is fine this way. If there will be no complaints, I would like to start the vote
sometime next week.
Regards,
Máté
