The various .pl files in /usr/share/perl/5.10/unicore are generated at
build time from the .txt files. The .txt files are also used runtime at
least by Unicode::UCD, possibly others. The chance for them to go out
of sync doesn't seem appealing.

A somewhat related upstream thread is

 http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2009-01/msg00585.html

which shows at least that UCD upgrades are not quite a trivial matter
for perl.

Decoupling UCD from the perl core would mean an extra maintenance burden
upstream (ensuring the code and tests keep working with different UCD
versions), and I'm not very comfortable proposing that.
