I've been looking at semantic-symref-filepattern-alist like a workaround 
for the fast that the major modes don't provide enough relevant 
information in auto-mode-alist (or, to look at it differently, don't 
provide such info in some other variable which the auto-mode-alist entry 
would be computed from).

From that perspective, storing the missing association inside the 
semantic-symref package seems suitable. But a more "proper" place for it 
would be better, of course.
