Yes. We are talking about current master, not about intended final
implementation.

You are talking about GRASS 6 support? What are serious regressions?

The Processing plugin may substitute "GRASS Tools" part of the plugin
(i.e. modules GUI), it cannot help  with:
  - mapset creation
  - vector/raster maps visualization
  - vector digitizing
  - region visualization and editing
The Processing plugin is good for users who don't want to use GRASS
data format at all. The GRASS plugin is GRASS GUI alternative for true
GRASS users.
