   We would need to define what it means to combine globally with defaults for 
non-trivial windowing. (Presumably that'd be a empty value for every empty 
window, so we'd need some way to enumerate windows.) If one wants to see 
combined values only when there is data, `without_defaults` should be advised 
and used.
