Once implemented, would the round/ceil/floor methods work as arguments to groupby too?

Sure. You could write, e.g., ds.groupby(ds.time.dt.floor('1D')).mean()

Are you in favor of renaming the current functionality todt.yeardate or some such for convenient usage?

I would be inclined to stick to the datetime methods/properties from pandas: https://pandas.pydata.org/pandas-docs/stable/api.html#datetimelike-properties
