It is also a little bit of an issue for people who distribute stand-alone
applications written in Perl and bundled into a single executable with tools
like PAR, PerlApp or Perl2Exe.

Right now you can fine tune the size of your bundled Unicode support by
for example removing the 4 big tables for the major Asian scripts and
still have Unicode support for all the European languages.  Having just one
huge table would likely make this impossible.

Having such a big footprint is also a huge drag on application startup
time if they have to extract the table to disk every time the application is
run (yes, you can leave the files behind in a cache area, but some people
prefer not to leave stuff behind when the application exits).

I would also be curious how good those 7-14MB could be compressed, as that
too would make a big difference for the actual filesize of packaged apps.
