seedlet and full site editing

Introducing Seedlet – ran across this article on themeshaper.com, the theme seedlet was used as a theme for full site editing demo in the video. perhaps this is a major reason for the requirement of php 7.3 by this theme

even though the www.ads-software.com version requires php 7.3, the wordpress.com version does not and the theme code is available from both sources.
