Note various to/from string and date types use locale info that is also
duplicated. Basically everything that uses RTL state + anything that uses
compiler generated tables. (there is two times RTL state and there can be
two copies of those compiler tables).

Some of it is somewhat documented on


specially the "What do we need them for? What's "special" about packages?"
