Support for Core Components 2.18 and 2.19 on AEM 6.4

[Kami6e]

Hi, I see in this announcement from last year that there will be no support for AEM 6.4 after Core Components version 2.20. Does it mean that the versions 2.18 and 2.19 are still compatible with AEM 6.4? Has someone tried it and/or can clarify if it's compatible?

It is not completely clear looking at the announcement above and the documentation here: https://github.com/adobe/aem-core-wcm-components#system-requirements which lists only AEM 6.5 as supported for the current Core Components version.

Thanks in advance!
