We are missing Attribute filtering and some scenarios in the accessibility filter, see: #16817 (comment)
For Attribute filtering I think it makes sense to have a filter dedicated to it that ignores compiler generated attributes and a default list of attributes that shouldn't contribute to API Compatibility like EditorBrowsableAttribute. Also it should be able to take a list of attributes to ignore based on user settings.
