There's enough to give you a firm grasp on things without being overwhelming.

I would love to see the designers put something like that in a future book, but given the release schedule that'll probably be in like 2025 or something. Maybe I should write some myself...
I'll admit to having turned off 5e long before XGtE, but this does remind me of something I tried to do with 5e skills. There's a couple that I would change if I redid it now, but it's certainly something I'd like to have seen in the core rules.
