Basically what I do is just create a schema class on a per app basis 
that only pulls in the classes we're using for it. An example would look 
something like:

package <Company>::App::<AppName>::Schema;

use strict; use warnings;

use parent 'DBIx::Class:Schema';

__PACKAGE__->load_classes({
    '<Company>::DBIC::<Db>::Schema::Result' => [qw(User Post Category)],
});
