Personally I think this is true. C++ is multi paradigm and can be effectively used with many different subsets of the language and those subsets still interact well.

However that opinion is kind of a minority. There are a lot of people in the community who don't want to have to learn new features just because a dependency happens to use/expose them. I don't personally see the issue with it.

I'd rather learn std features any day over non-std features. It's just a better use of my time because they work everywhere and someday I might need them. However again not everyone shares this opinion.
