The MR looks correct to me.

Can the MR be updated for 10.6 please

I will leave for 24hrs to see if @jcontreras wants to fix #16.

The MR applies to 10.6 , this is a one line change that is not tested.

If we aren’t going to run against the pipeline should it just be self RTBCd

This is a line that is in a list of deprecated properties, it very unlikely to get accidentally changed in another commit, so I don't think a test is necessary. Leaving the tag though for others to comment.
