It requires every file to be processed with md5sum twice during
installation; the checksums are 128 bits (16 bytes) long, and come
to 32 bytes when they're stored as hex in the dpkg databases.
Apart from some order-n^2 algorithms used in dpkg's conffiles
processing, which could be changed, doing this would double the
size of the /var/lib/dpkg databases and reduce installation speed
by a factor of 3 or 4, I think - more on low-CPU systems.
It would be nice to have a debian configuration *option* to maintain
all files as conffiles. Not for release 1.1 of debian, however.
