DNS Flag Day and Yandex DNS - do I need to change something for my domain?

Question

Domain Name System

The domain is served by Yandex pdd (or connect is now called) - do I need to do something in the light of DNS Flag Day?
I trust Yandex, but if you go to the dnsflagday.net verification page to check the domain, it says:
Minor problems detected! This domain will work after DNS Flag Day 2019 BUT it does not support the latest DNS standards. As a consequence, this domain cannot support the latest security features and may be an easier target for network intruders than necessary ....
Although while I was writing this question - the service response to one of the 2 domains suddenly changed - it became written that the domain is completely ready, although a few minutes earlier the problem was also described. Maybe some changes are being made right now?
I decided to wait for now, and you do something?

Answer 1

This domain will be operational after DNS Flag Day 2019

What else do you need from Yandex? The domain will work, mail too. Until today, you have been living quietly without the latest dns functions, why should you worry now?
