Facebooker talk - Jan 2009 - a constatation on fb:name FBML tag

Hi all,

I just constated something strange (for me at least) with <fb:name />.

If you use a group gid as the "uid" param, it works too. The group  
name and link get rendered.
On the wiki page (http://wiki.developers.facebook.com/index.php/ 
Fb:name) it is said that it works with user ids and page ids.

So does it mean the "id space of facebook" is shared between all types
of objects (pages, users, groups, events, ...) and the plateform is  
able to determine what type it is (deterministically) according to the  
given id?
By the way, if you access the user profile page with a gid as the id  
you get redirected to the group page, so it seems to be the case.

Do you think I can rely on this in my application and so use the  
fb:name tag to display groups names/links (which would be a great  
performance ehencement).

Maybe all of you did know that and that''s just a dicovery for me....
