Thanks @erichorwath, we will take care of updating the different internal tools and checks relying on that property. Please note that action could take some time. To prevent Stale Bot from closing the PR, we'll add the on-hold label.

@carrodher thank you for addressing this question, I'm a colleague of @erichorwath.
Just wanted to check if you can share any update on this issue, with respect to the updates on the internal tools and checks.
thanks in advance and best regards.

Hi,

I'm afraid it is still in our backlog. As soon as there are updates we will update this ticket.

[dellagustin-sap]

Thank you @javsalgar for the update.

Hi, @javsalgar, @carrodher, just doing my periodic check on our open issues.
Any news on the updates of your internal tools that are a dependency for merging this PR?

[carrodher]

Hi, apologies for the delay. Due to other team priorities, this is still in our backlog, but we’ll aim to get to it as soon as we have more bandwidth.

@carrodher thank you for the reply, and no need to apologize, this is an open source project and we understand we are not entitled to any kind of support.
I hope you don't mind me asking now and then, it is just to keep the status of our (low priority) internal task, that depends on this fix up, to date.
