I've seen more recent statement where Fr. Jenkins articulates a similar position re: sedevacantism. I agree that Bishop Kelly has been the strongest impetus against the Thuc line.
This past Sunday I assisted at an Oyster Bay Mass. The priest included in his announcements, for the sake of anyone new, that nobody attending the Novus Ordo in English or Latin can go to Communion. There was no hint of forbidding those who attended Thuc-line Sacraments. This appears to be easing up.
