There's a more in-depth discussion of why these are being deprecated here: https://security.googleblog.com/2018/10/modernizing-transpor...

TLS 1.0 relies on MD5 and SHA1 and is no longer PCI-DSS compliant.

In case anyone is curious: TLS1.1 was released in 2006 and TLS1.0 was released in 1999. Fun fact: TLS 1.0 re-uses the SSLV3 version sequence for interoperability. 0x0300 is the 2 byte sequence for SSLV3 and TLS1.0 got 0x0301. Lack of knowledge of the above once led a less experienced me to use SSLv3 for an app in 2011 because "the number was higher".
