Exactly, the marketing/communication/sales people need those bits in a UI, they need tools to analyze those bits easily, mark them for specific analyzes and to share reports.
Sure, and there's definitely value in that. I can't speak for other products, but GoatCounter intentionally doesn't try to solve every possible analytics use case.
Adding advanced features frequently comes with the trade-off that it makes things harder for people who don't use those features, so by limiting the scope it gets easier/better for some, and worse/harder for others. I found this is the case for software in general.
There certainly should be an UI to quickly compare how the current quarter is doing compared to the last quarter (I wrote some code for that last week, but not done yet), but doing stuff like adding extra search parameters like "from mobile" and "from Netherlands" seem awfully specific to me. While certainly useful for some, most people are not hard-core marketers and adding stuff like that is just "noise" for a lot of people which makes stuff harder to use for them.
Matomo can do all of that, and I also found it hard to use.
Or, tl;dr: Matomo is already good at being Matomo, let's do something different :-)
