[Plan] Roadmap for 3.0.x (D11 compatible) stable release

Problem/Motivation

The Migrate Files (extended) module is currently in an alpha state (3.0.0-alpha1). While the module is functional, many production environments and organizations require modules to have a stable release to ensure long-term support and eligibility for Drupal Security Advisory coverage.

Proposed resolution

I would like to ask the maintainers what the current blockers or requirements are for the module to move from alpha to a stable 3.0.x (e.g., 3.0.1) release.

Specifically:

1. Are there any critical bugs that must be resolved first?
2. Is there a specific set of features or modernization tasks (like Symfony Process integration) required before a stable tag?
3. What is the status of the security coverage application for this project?

Understanding these requirements will help the community understand the current health of the module and the path toward a stable version.
