Is the 'stm32-external-loader' repository still maintained?

The stm32-external-loader contrib branch has not been updated in over 5 years.  There are currently 7 open pull requests with updates to support new flash ICs.  Some of these PR are 4 or 5 years old.

The ST MOOC external loader course encouraged developers to add their drivers and many have.  Does anyone from ST know why these updates were never considered for the contrib branch?
