It also depends what's the biggest priority - I would assume there is a bigger 'quick win' from becoming more reliable at single-intent actions from a market/customer experience perspective rather than pursuing highly complex multi-intent statements. >99% of commands will be single intent, and they probably work 80% of the time at the moment, so getting those to 99% will have a much bigger short-term impact than focussing on solving the 1% (with the added benfit that once you have solved the first case of getting single-intent right all the time, solving the second more complex queries will be easier as you will have built a more robust base).
