That is a very good way to look at it.
Now, I am not a C++ dev, but how much effort would it be for a team to pick up C++ 20 if they only had worked with was C++ 11?

The functional programming parts and expansion of compile-time metaprogramming (constexpr/templates) are probably the biggest new features, but you probably aren't going to use the more complex parts.
IMO the biggest changes in ergonomics for application writers are:
* better iterator-based algorithms and iterators becoming more powerful than indexes and pointers
* new helper objects like string_view that let you work more efficiently
* functional programming and passing lambdas around is possible
* "override void foo() const noexcept { ... }" - all the extra keywords (override, const, and noexcept) help you with correctness
