Good, get rid of the whole "ecclesia dei" commission/law/motu proprio, which is a distraction and a subversion of the only law that matters (and which is still in effect): Quo Primum.
Let +Francis gut the traditional movement and see how the younger generations react - many of whom have discovered the TLM and see the emptyness of the novus ordo. Let all the "conservative" catholics in the novus ordo truly see the evil and anti-catholic aims of the V2 hierarchy and what V2's real purpose was - destruction of the true faith. Then, maybe they'll wake up! Maybe they'll leave the V2 church!
Meanwhile, Quo Primum remains in effect, it's permissions to say the TLM remain, it's command to ONLY use the TLM missal remains and it's obligation for catholics to avoid any other missals, still stand in force, under penalty of sin. Getting rid of the "ecclesia dei" fiasco will just make the battle lines clearer.
