Having types isn't something we can just say we have.  It requires a lot 
of plumbing changes to the existing code to support the concept of SG 
types--much more than the changes required to add an ability to request 
no-fallback searches of SGs via RemoteFile, which (as I'm sure you've 
noticed) requires quite a bit of code changes.

There is a plan to add support for SG types, but it requires someone to 
write all the code, which requires time.  Before that code is there to 
identify, enforce, and support SG types, making assumptions about what 
is in the directories of an SG will only cause issues with (at least 
some) users' systems.
