The future of Team Kodi PPA after Nexus



I see that from the official KODI install guide for Linux that Team Kodi PPA is no longer supported.  My questions is from a software security perspective.

There are bound to be thousands of KODI implementations that don’t upgrade past Nexus out there that will no longer be receiving much needed patches.  Is the plan just to have these systems age out and eventually get decommissioned?  Or is there an effort underway to eventually get these systems upgraded?

Is the problem that the Team Kodi PPA maintainer stepped away, and there was no hand-off of admin credentials, so there is now way to utilize the existing PPA implementation?  If so, is there an effort to implement a new Team Kodi PPA, and users will just have to make a tweak to their /etc/apt/sources.list ?
