Moreover, extensions that continue to use this behavior are required to adhere to manifest v2, and support for that manifest will likely eventually be deprecated. Chrome blocked the store from serving and updating manifest v1 extensions after a deprecation period.
Google rapidly deprecated version 1, from Chrome 18's release adding version 2 in March 2012 to blocking updating in March 2013, to removal of all extensions that had not updated from the Chrome Web Store in September 2013.
If Manifest v3 follows a similar trajectory, Chrome is on a path to remove uBlock Origin from its web store in 2 years.
