Status of this note:

New name was announced in February 2022.

Change was reflected in OSM as proposed:name
https://www.openstreetmap.org/changeset/117456806

As of September 2022, the pictures show no single sign anywhere here
https://www.mapillary.com/app/?pKey=1306978426786889
I also have a private video from early October 2022, no sign either.

Cannot find any single online resource telling us whether the name was effectively changed.  I would expect the mayor to proudly show a picture when unveiling the sign, or something like that.  The only documents are about the February 2022 proposal.
