I think those hidden problems are quite serious.

Good.  May be it makes sense to check kmer with this.  It could be
that there are other hidden problems which simply did not came into
effect.

Good.

Lintian warns if the amount of architecture independent data in an arch
any package is above a certain percentage of the package.  May be there
is a way to craft a nifty rule in lintian to detect if the same data are
spread over different binary packages.  I think that's just useless if
the data set is not "really" small.

That's very good.

It would be very helpful if we could make some progress with this.
 
Kind regards
