I don't think you understand the point I was making.

One of the most common complaints, also prominently presented in this thread,
is that when a library, like the ranges library, is added to the standard,
that means that people who need to maintain other people's code will start
encountering code that uses that library, meaning that it's yet again one
additional thing they need to study and learn and understand, even if it's
something they themselves never use.

But how exactly is this different from such a program using some third-party
library which, quite often, you have never used and thus need to study and
learn so that you can maintain the code that uses it? This is extremely
common, given how many millions of third-party libraries there are out there.

And, quite often, there are many different libraries for the same task,
and different programs will use different libraries. Thus often it's not
enough for you to learn one library for that particular task, and instead
you may encounter several of them.

A library being in the standard actually makes that better: The more
people use it, the less you will have to learn when maintaining their code.
