Is the add-on VPMS official?

Hello everyone,
I’m taking my first steps on Capella and I’m using the vpms add-on.

My problem concerns the validity and officiality of the vpms add-on. Now vpms, although there is a webinar about it and many topics on this forum, is not official (available on the add-on page of the capella site). Why isn’t the add-on offered/supported by the Capella team?

Is there an official link to download it?

Thank you in advance for your help.
