I guess that really depends on whether the rules are written to properly
constrain the writes to the view to the set of rows visible by the view.
For example, if a view v1 selects from a single table t1 constrained by a
search condition, and I do UPDATE v1 SET ...; without a condition, does
that affect all rows in t1? If not, then both our proposals are
equivalent, if yes, then the it's the user's fault, I suppose.
