Local config folder must be in the path at config time

[Greg]

When the settings files are loaded (according to the local /plugins/../config/host.config.php files), the local config folder (/plugins/.../config) should be in the path to allow "single name" files:

$configuration['host']['www.first_site.com'] = ‘first_site’;
↓
 /plugins/MyPlugin/config/first_site.config.php

[Greg (gregfr)]

This is not possible since at the time the entry is used, all "host" configurations have been gathered and merge.
