Is iterator_facade still relevant in C++11, C++17?

Hi,

This is a bit theoretical question, but I'd like to collect some opinions.

Considering sequence of C++ versions, around where, if at all,
boost::iterator_facade shines less and becomes less relevant?

In other words:
- If you had to implement iterators in C++11, would you use it?
- If you had to implement iterators in C++17, would you use it?

Has anyone observed performance issues when using iterator_facade?

Best regards,
