Multiple Features support is not so simple.
For example, if you need such functionality in the PrestaShop you need to buy additional module (like this
http://addons.prestashop.com/en/bulk-update-prestashop-modules/6356-multiple-features-add-features-without-limits.html) in this case some changes in table structure will be changed by module. That's why it's hard to support unlimited number of additional modules with own logic.
When such functionality will be added to the PrestaShop - we will be able to maintain it at the level Store Manager for PrestaShop.
