We implemented MTA-STS back in September 2018.
Since yesterday, Gmail deliverability went straight up for clients with MTA-STS policies published on their DNS.
We also noticed that it works better with paid SSL certs on the host rather than free SSLs from letsencrypt.org and such.
It seems it'll become the new "requirement" pretty soon with better results than the previous weak auth techniques
