But eventually you'll find the power users who do business critical stuff in excel sheets that you notice can't be done in any other way, and if you stop doing it then people aren't paid in time or whatever.
This doesn't mean it's a good idea to not try this. But Microsoft also aren't dumb. They know exactly how common this is, and what fraction this is. And they will make sure that it costs little more to keep the Microsoft products across the org, than it costs to keep them for specific users and deal with the mess that happens.

In my experience, non-basic formulas are beyond 99% of people and they use it simply for adding stuff up in a grid.

The most complex operation some people do seems to be lookup tables.
