You assume that the interfaces are
1) user controlled
2) is not used outside from your own environment.

Both valid use cases but invalid assumptions. GUID needs to stay user 
selectable otherwise you loose the ability to implement interfaces for 
3rd party applications (banking, stock exchange, ms office etc). 
Interfaces are compiler agnostic you might import them to use a 3rd 
party library (eg. ADO) which has its own GUIDs that you must not change.
