I think we should have a fairly high bar for deviating from those.

For those who think ` bool(xr.Dataset(dict(x=False)))` should evaluate to `False`, what do you think `dict(x=False)` should evaluate to?

IIUC, this is somewhat of an edge case — it's only possible to coerce `DataArray` to bool when there's exactly one element. (Not that we shouldn't resolve)

> This question seems to me to be conceptually similar to the question I described in #3315: ""Should we treat a named DataArray and a single-variable Dataset as if they are the same?""
