At DrupalCon New Orleans, a workflow was discussed that would allow a profile would contain the config sync directory and this full config export should be used at install time. This would be facilitated by allowing an install profile to declare
config_install: true in its info.yml file.
To be clear, this issue would only pertain to install profiles. The separate use case of allowing a site to be installed from an existing configuration export which is not part of a profile is covered in.
