Generally "method attributes" and "handle attributes" are quite
distinct. The one place they're not is the connect() methods that create
a statement handle.
It's an unfortunate historical accident that methods returning statement
handles can't also take handle attributes in the way you describe.

If you're interested in tackling this (for which I'd be delighted) then
we should start by defining the semantics and considering any backwards
compatibility issues.
