I don't know if we want all of them to be autoloaded, but I see no
reason not to autoload some, those which are used by preloaded code.

The way to hell is paced one step at a time.  Those 3MB were not all
added in one go, they were added one file at a time.  So we need to
examine every single file we want to add and decide on a case by case
basis, otherwise we will get 6MB instead of 3MB faster than you can
say "make autoloads".
