I commented on that issue (4374) and explained my view on that topic again.
Do you think the plugin way would be easier (knowing that it is not necessarily
faster)? It seems to me that the implementation into the postgres data provider
of QGIS might have a undefined time horizon.
I could really use that feature and have entry-level python experience and
never developed a QGIS plugin.
Are there more people out there who would welcome that change?

I found this one, for allowing the specification of a "bbox" column
to use for filtering:
And this, to allow keyword substitution:
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"...
