In early versions of AngularJS 1.5, it was possible to use restrict: 'A' for component() method, and I used it widely in my code. Breaking change came with 1.5.0-rc.1 quantum-fermentation (2016-01-15), where only restrict: 'E' became permitted, but I missed it (I think not only me) because I stayed with one of the previous 1.5.0 versions. Today I updated Angular's files to 1.5.0 final release and components with restrict: 'A' weren't visible and it took me a while to figure out that I have to replace attribute usages to element usages. Maybe, to avoid confusion, it should throw an Error when component() method meets restrict other than 'E'?
Thank you in advance for looking on this post.
