That's already "in the system". Let's discuss, for example, m68k (my favourite 
broken arch). 

Now: 
* There are some stable keywords hanging around, but nobody cares about them 
except the m68k arch team (= Mike).
* All m68k profiles are "exp".
Repoman happily ignores it (unless you use -e).

In the near future:
* m68k is marked "testing" in arches.desc
* All m68k profiles remain "exp"
Repoman *still* happily ignores it (unless you use -e); if you use -e, it will 
test it with ~m68k=m68k.

In the far future, given the arch team is intersted:
* Upgrade profiles from exp to dev or even stable -> repoman will test it more, 
but still using ~m68k=m68k. 

So, whatever "non-support for broken arches" we have now will keep existing. 
Just that migrating away from it gets easier.
