Yes, but say that EmperorQ as we call it is version 5 of Emperor (could be 6, whatever). SubClub makes it name-embedded, so existing owners pay the necessary fees to make their Emperor v5 name-embedded.
Now there’s a development and the Emperor script gets updates. It is now Emperor version 6. Previously, that upgrade was free. But now it would mean we have to rebuild our name-embedded Emperor to the new version 6 script, which would once again cost.
See what I mean? It would be similar to if one of the Q store modules got updated. You’d still have a license for that module, but in order to enjoy the update, you would have to rebuild your custom. A name-embedded sub, even if its modules have been pre-selected by SubClub, is still technically a custom.
