Quality often goes down. That request process results in you getting what you ask for, not what you want.

Think about anything that you do in Excel. In what scenario do you roll with exactly what you initially start with?

I just did a preliminary capital forecast in Excel. I could have used something like Google sheets as well, but beyond that, the lack of flexibility makes purpose built solutions less able without specialized people that I don’t have or domain knowledge that I don’t possess.

This. Excel democratizes computation in a way that code has yet to do. If something breaks, non-technical people can just jump in and fix it. If they need new functionality, same thing. They don't have to bring in (or retain) a specialist. That's an incredibly powerful proposition.
