>PowerQuery doesn’t really support things like subtotals easily,
Subtotals? I was used to using GROUPING SETS with Oracle SQL, and found I could roll my own in Power Query. It's a good example of exactly why I like it.
Also, Power Query doesn't prevent you from using the regular table total feature or a pivot table based off of the Power Query output.
That is, even if Power Query doesn't provide all the subtotaling features you'd like in the way you'd like, it doesn't restrict you from anything, does it?

I do use it to do all sorts of ad hoc calculations - for instance, it can ingest PDF files or HTML with tables.
It sounds as if you're saying it's too complicated for really trivial calculations?
