I don't really see the point, yet: we don't offer any alternative 
functions, and if the user is going to write one, `setq' is just as easy 
to do.

Further, applying this kind of minor change (and finding it important) 
seems like it would indicate that xref is kind of "stable", which it is 
not, so far.
