Could this not partly be because up until now Emacs didn't supply such 
commands? (although as of the CEDET merge there is actually 
'semantic-ia-fast-mouse-jump' but since Emacs went in the xref direction 
I suspect few make use of it).

And whether it is in one's interest to use the keyboard or the mouse for 
these kind of commands is still is an open question (among others, see 
[1]). My observation from co-workers seems to indicate that using the 
mouse for this kind of functionality is very common and I think having a 
default binding would improve its discoverability (although I am aware 
that this is hardly an area of focus in Emacs).

Unless any of the above makes you reconsider I will not argue against 
this. I have submitted a pull request for similar kind of functionality 
to CIDER ([2]) where we have decided to add a default binding along with 
it so I was hoping to harmonize these with Emacs' xref (which CIDER 
doesn't make use of at the moment), but CIDER being out-of-tree there is 
obviously more leeway.
