@jsandas The acme module is slated for removal as a community maintained extension in 3008.0. Do you have any desire to maintain it?

[twangboy]

This module and its associated states and tests have been transitioned to community support and are no longer maintained by the Salt Core team. The code has been removed from the Salt code-base and can be found in this repository: https://github.com/salt-extensions/community-extensions-holding/

There is currently discussion and work being done on the salt-extensions Discord channel (https://discordapp.com/channels/1200072194781368340/1208165123240370197) to document and build the infrastructure for community-supported salt extensions. There is also a Salt-Extensions Working Group that takes place on the 1st and 3rd Thursday of every month to coordinate salt-extension efforts.
