Let's summarise the discussion and decide what shall we do with it.

The proposed patchset introduces two new restrictions:
1. Packages that mustn't be noarch because of essential payload
   mismatch on different architectures.
2. Packages that must be noarch because their payload is essentially
   the same on different architectures.

The only drawback of the first restriction is that the proposed
implementation fails to filter out non-essential differences, e.g.
timestamps and random html reference names.  That is, in its current
form it would stop some grave packaging bugs, but also it would forbid
some legal noarch packages.

The second restriction was reported to have a major impact on packages
because it affects about 600 source packages, and changing rules to
break so many packages due to optimization purposes doesn't look good.
Some ideas to avoid extra dumb work for packages were proposed later,
but no implementation have been arisen yet.
Also, the implementation in its current form may mistakenly decide that
packages have to be noarch while they really shouldn't, e.g. cpuburn.

That is, I'd be glad to make these restrictions taken effect when these
three issues are dealt with.
