I suppose so.

But it wasn't ideal either. For instance, with C++, completion couldn't 
offer unqualified method names, because the indexer always qualified 
them. It was up to the user to figure out that typing an unqualified 
method name and pressing RET would still yield something useful.

Another thing to consider is the possibility of merging Ex-Ctags and 
Etags in the future. Compatible behaviors would make it easier on the users.
