It's probably up to CEDET developers.

But the UI itself is one of the benefits. If the old one was considered 
superior, the new API could have been introduced without really changing 
the UI.

There seems some confusion here: you do now invoke xref-find-function. 
It's not a function anyway, it's a variable, which different backends 
can set to implement the backend interface.

You invoke different commands from the xref package. Try typing `M-x 
xref-find- TAB'.

I really don't remember stating that in this discussion.
