nice article you shared!
I didn't know about Badgr (https://badgr.org/ or https://badgr.com/). At their .com website they advertise being the solution to badges on Canvas since recently.
For what I understood of the article, Badges are not dead or dying, it's just changed home and direction.
The IMS is the the same consortium that is in charge of LTI, another standard that Moodle supports.
The IMS has a certification program for software that support their standards.
Moodle 3.3 is on the list for the LTI (https://www.imsglobal.org/cc/statuschart/lti), but is not on the list for Open Badges (https://www.imsglobal.org/cc/statuschart/openbadges). The Badgr is on the list and for consequence, Canvas is implied.
It would be very nice to see Moodle on that list and also newer versions on the LTI list.
We can discuss that further (and ways to achieve that) if it makes sense for the group =)
