I have some fears here. It seems everyone's first thought when they think
about updateable views is to think about constructing rules on the views.

How would that approach help with inline views? Things like:
UPDATE (SELECT a+b AS x, c AS y FROM foo) SET c=1 WHERE x = 10

It seems like starting with these types of views in the backend would be more
productive than implementing something in rules. Once postgres can handle
inline views it should be trivial to handle persistent views just like they're
handled on selects.
