Plugins and themes use a separate prices than core, and so are not affected by this at all, really. For plugins, you can turn on auto updates yourself as of 5.5 and that's pretty much where that will remain for a while. There are no plans to start auto updating those outside of that switch functionality.

For themes, auto updates are different and not planned yet at all, because of the inherent differences there. One would need to detect changes to themes first, since not everybody uses child themes, and that needs a lot more thought. Themes are far more prone to modification.
