As I understand the situation, it may be that the interim fixes will be sufficient to get this risks patched to a level of security with which Chris feels comfortable with deploying the extension to more wikis and continuing to use it on ENWP while a long-term plan for fixes or system migration is developed.

I am hoping that Luis is involved in the review of this situation, because he is the one who is in the best position to make resource adjustments and/or ask for resource adjustments from Lila in order to address this situation.
