Circling back: the fix on 2.7 seems to work for me. Note that I did need to run drush updatedb which ran add_service_definitions from memcache_admin to clear an error that appeared.

Seeing this same issue. It's causing issues on specific pages with Big Pipe as well because it is failing. Some kind of conflict, not sure with what yet, but reverting seems to solve the issue. I'm continuing research, but we're still running Drupal 9.x so I'm betting that is part of the issue an an update to core may resolve.

Pushing for a full release of this fix. Our sites avoid dev versions as potentially unstable, and this is playing havoc with our testing pipeline and requiring significant workarounds for non-production environments.
