Social Media Tab in Page properties removed

Why was the Social Media Tab in Page properties removed? It was very useful to create OG Tags. But now this feature is missing. Because there is no alternative for OG Tags. So what should we use now?

Here is the commit for removing, but no reason why this is deprecated and what to use now:
https://github.com/adobe/aem-core-wcm-components/commit/474dce1aaea7dc508b747805fc429838bb058f31

**Environment**
- AEM version and patch level (AEM 6.5 SP12)
- Core Components version (2.19.0)

Start with commit 474dce1aaea7dc508b747805fc429838bb058f31 and compare the Social Media Tab behavior in AEM 6.5 SP12 with Core Components 2.19.0. Determine why the tab was removed and identify the supported replacement for creating OG Tags; done means the deprecation rationale and alternative are clearly documented.
