Notes on extensions
The extensions created often affect others but not known. I propose using the experiences and give individual notes as: 0-5, 00-10; a, b, c, d ...
Please define more clearly what you are referring to. Does this mean a box that displays something like: “This extension may conflict with extension XYZ.” ?

Yes, as Joomla is formed by parts of the core, would be a way to clarify the incompatibility of components, modules, plugins and templates.
The greater the incompatibilities lower the rating.
