Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Note: this tasks can be split up once we get feedback on issues, for now this is to discuss changes to make.
Note: while particle system for eg: has 'simple' brush types like this, grease-pencil sculpt brushes are more advanced and duplicate more of what we have for regular brushes used elsewhere.
Lower Priority
Internally grease pencil sculp is called:
GP_BrushEdit_Settings
,GP_EditBrush_Data
,GP_BRUSHEDIT_FLAG_APPLY_UV
)GPENCIL_OT_brush_paint

During the development, we tested the use of a brush cursor with the size of the brush and this had two problems:
a) The cursor was too intrusive when drawing. After a lot of test, a small point was the best solution.
b) The size of the cursor is not a real representation of the size of the final stroke (it's the same if you get a real pixel size not implemented now)... the problem is teh stroke is projected and maybe the distance to the plane makes the stroke thinner.
When you select a material, all brushes are set to this material except materials pinned. The reason to do this is that a type of "stroke" is the combination of material and brush, so to get some artistics effects you need define a combination of both. If we link the material, when you append a brush to new scene, you get the material too.
Not sure what you mean... add new strokes?
This an error of the default scene. The default value must be 1.0
Yes, the reason is this is legacy code and we haven't time/resources to redo all this system. This is a future ToDo.
Yes, some is legacy code and some new, so we can harmonize the names.
Again, legacy code, we could rename it to something like GPENCIL_OT_sculpt_paint

@pepe-school-land @mendio Thoughts?
Your answers seem good to me @antoniov
Among all the issues, IMO the most important is to convert the actual Gpencil sculpt operators to real Blender brushes as soon as we can. I totally agree with that, is the way to go for better consistency.
@antoniov - is there anything that makes grease pencil sculpt using regular brushes complicated?
In this case why not use an absolute size for brushes?
If you want to paint a weight (0.5 for eg) onto an existing stroke, as far as I can see this isn't possible currently.
In that case it's a simple fix.
Is this such a big task? Or is there some feature that makes this more difficult then using regular brushes for gpencil-paint for eg?
The hassles we get from having a separate system also give some overhead.
Could we try do this renaming before 2.8x release?
Otherwise people will end up with keymaps using the confusing names.

I agree that the many types of brushes is confusing, I think we should ideally get down to three types of brushes :
I feel that Blender is missing a rich collection of brushes, especially since the move to 2D animation : we're competing with software that has hundreds of downloadable brushes both for raster and vector painting. With many redundant brush systems, it is going to be hard for users to create and share their own collections of brushes...

I have an addition to this. (Please let me know if I should open a separate bug report for it.)
I've noticed that Weight Painting on Grease Pencil also respects if "Selection Mask" in Sculpt Mode is turned on. This can be quite confusing because the option to turn it off is not available in Weight Painting and the selection is also not visible.
