Vlad Kuzmin (Ssh4) added a comment to T81662: Camera projection mapping for brush texture.

For example, distortion model does not exist on its own. It is highly coupled to a specific camera and its configuration used when shooting a footage. Currently such coupling exists in the Movie Clip datablock, with tools to estimate the distortion model done in Movie Clip Editor.

From this point of view, it seems logical to build a workflow based on use of movie clip datablocks. This solves the problem of non-reusable parameters stored in brush datablock, and solves problem of adding parameters to camera which are only usable by painting.

How from artists, matte painter, or accets creator point of view images that use camera view as a projection (we can name them Projector Projection that is more like a Light with color gel on it) images are related to Movie Clip? Or you only about datablocks, not about UX?

Be aware that design decisions need to be approved by reviewers and module owners. So you can of course to implement it however you want, but it's won't necessarily be accepted that way.

Can you clarify this point? @Ivan Perevala (ivpe) definitely can’t make own decision on final design. And If you know any plans in upcoming changes in this module please share them to Ivan.
If someone already working on refactoring this area in Blender and that code can interfere with that refactoring, we definitely need to bear in mind that upcoming changes to make this work usable in them too.
But if there is no plans for near future, and no Blender foundation coder[s] assigned to that tasks, Ivan as independent coder can only add new feature with maximal compatibility with existing code and current blender user experience.
Also sorry, English is not native for us, and ultimate word “decision” just mean, opinion that such way is more usable. :)

@Brecht Van Lommel (brecht)
Definitely for this moment camera projection is not so usable without preview.
And @Ivan Perevala (ivpe) have this Milestone 3 Preview.
Only issue that Camera Projection can be used without preview. But have preview without camera projection implemented have no reason. So this is only matter of priority.
And for this moment when code for camera projection is working, and we can brush up UX for this tool.

Sorry, but is it possible speedup patch review? With old Preferences dialogue and old open window their position was not so important. But in 2.81/2.82 modal window is default and always adjusting their size highly impact workflow speed.

But this is a Bug!

3D model rotating around 3D cursor and there is no way to change or disable this behavior without switching back to Object or Mesh edit mode.
(...)

I didn't understand what you meant by "there is no way". You can disable Lock to 3D Cursor in those modes.
This seems to be a design issue but not really a bug.

Fill with anything, like noise or gradinet.
