Could you elaborate?

It's how I understood your proposal and how Seth seems to have
implemented the FE build system: ATM, one build failure on one of i386,
x86_64 or ppc prevents building a package for the other architectures
and therefore disqualifies a package from being upgraded.

That's reasonable. We should try to provide the same packages for all
supported architectures, but we should not let packages failing for some
architectures block the package for those it does not fail.

In practice, developers will only have access to a limited set of
architectures, in some cases developers do not/do not want to support
some architectures, so ... there will always be "second class citizen
packages" on some architectures ...
