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.remarpro.com version requires php 7.3, the wordpress.com version does not and the theme code is available from both sources.
