Was just going to mention this as without a replaceable hangar any damage to the integrated hangar will cause great issues as unlike an integrated steel hangar which can be bent, bending an aluminium hangar back into shape can result in stress risers and breakage.

This is pretty common on many entry level Aluminium bicycles and a long as one does not crash it there is not an issue but once you do it is often enough to write off the frame and sometimes you can use a claw hangar to make a repair if enough of the dropout is left.
