That is in your opinion it is better to extend than to augment. I agree
that this is for many case the best way. A problem with this approach is
that you cannot modify base classes of ExtJS this way. You need to
extend all components/widgets if you want to add a tiny feature or make
a slight adjustment.

Maybe this can be decided on a case by case basis.
