Apex 4.2.1 - Reserved application ids?

Question

APEX 4.2.1, Oracle 11gR1
We have application ids 200 and 201 in a workspace. We needed to clone 201 from a prior version in VSS. So I pulled out the version from VSS, ran the following snippet to install it as application 202 (id is not used in the instance) as follows
DECLARE
    l_workspace_id INTEGER;
begin 
  select workspace_id into l_workspace_id  from apex_workspaces where workspace = 'FOO';
  apex_application_install.set_workspace_id(l_workspace_id);
  apex_application_install.set_application_id(202); 
  apex_application_install.generate_offset; 
  apex_application_install.set_application_alias( 'F' || apex_application_install.get_application_id );
end;
@f201.sqlNo errors. I type in 202:22 in the Search box at the top right of the Builder, the page looks fine. I click on the Application Builder link in the breadcrumb and find that 202 is not listed in the list of applications! I scratch my head. Query APEX_APPLICATION_PAGES for 202:22 and it does exist. But there is no entry in APEX_APPLICATIONS for 202! I scratch my head even more.
Digging into the source code for APEX_APPLICATIONS and a process of elimination, leads to the offending predicate in the where clause.
  /* keep this not exists */
  and not exists ( select 1
                     from wwv_flow_language_map m
                    where m.translation_flow_id = f.id);
The comment is part of the code, not mine!
Sure enough, there is an entry in the wwv_flow_language_map table with a translation_flow_id of 202.
So I chose some other id instead of 202 to install the app and everything is fine.
What is going on here? Are certain application ids reserved? I can understand that the Builder related app ids (4000, 4500, etc) are reserved but I am not sure I understand how I can have application ids 200 and 201 in my workspace but 202 is not allowed!
Thoughts? Thanks

Joel - Thanks for responding.
1. I know exactly zero about multi-lingual/translated applications in APEX but I am curious as to why (only) this one instance has these translation_flow_id in the range (183-221). I am guessing it is because I install the APEX Builder suite of apps into the workspace using the script below? If so, what should the script do differently to load just the English (en) language applications?
2. Just curious, what would the fix for this bug be? A change in the view definition for APEX_APPLICATIONS to tighten up that NOT EXISTS predicate?
Thanks
