      • [Oct 22] With latest changes to the team, and since this is upstream work the team is no more keen to tie it to a release
      • [2025/07/22] The Enhancement Proposal is merged. Working on the first code changes in the core autoscaler.
      • * [03 Jul] The PR is still open, but there appears to be agreement with the community, so it should be approved as soon as the maintainers can prioritize it.
      • [17 Jun] Targetting 4.21. PR open. it carries risk due to uncertainties of how fast things will progress upstream.

      Filing a ticket based on this conversation here: https://github.com/openshift/enhancements/pull/1014#discussion_r798674314

      Basically the tl;dr here is that we need a way to ensure that machinesets are properly advertising the architecture that the nodes will eventually have. This is needed so the autoscaler can predict the correct pool to scale up/down. This could be accomplished through user driven means like adding node arch labels to machinesets and if we have to do this automatically, we need to do some more research and figure out a way.
