That's a bone of contention.  I personally do not like to see C-files
overwhelmed by a sea of structs/tables and tend to ferry them off into
*-tables.h header files instead.

As the gate-keeper, what you say goes.  So if you insist we move these
450 lines of tables into the source file which references them, I will
of course do as you ask.
