I found this one, for allowing the specification of a "bbox" column
to use for filtering:
http://hub.qgis.org/issues/9516

And this, to allow keyword substitution:
http://hub.qgis.org/issues/4374

I guess the latter would deprecate the former.
Your comments on the ticket(s) would be welcome.

Well, I would want it :)

I guess a plugin could effectively change the query associated with
a layer so to filter by current bbox against an arbitrary column,
but I'm not sure what would be "quicker"...
