Another option is that all the Provides: part of type-handling is done
on dpkg. The current problem with the implementation:
- A rebuild of type-handling is needed each time a new architecture is
added to dpkg.
- Provides do not always work as an alternative. This require for
example type-handling to be installed on the build daemons
(technically it should be an Essential package for this to work).
That's why I am not really for more usage of type-handling, which IMHO
should simply disappear.
