While working on some custom property editors for a new application, I've realized that they support support Screen Components and Invocable Actions but unfortunately not Local Actions (as far as I can tell).  Are there plans to expand support to include custom editors for Local Actions on the roadmap?  Along the same lines, will we be able to build local actions using LWC instead of Aura in the future?

And somewhat tangentially related, the custom property editor feature is incredible and really allows a developer (or an ISV) to provide a bespoke and intuitive experience for their more complex Flow customizations.  Is this pattern something other builders (e.g. App Builder and Experience Builder) are considering or is it exclusively developed for the Flow container?  Thanks!
