- The five hindrances are overcome only by the attainment of jhana (at least the first jhana)
This statement is found in Tipitaka normally. All previous context in DN SubhaSutta is for preparing to attain Jhana. And we can found something like this in whole Tipitaka even in MN KayagatasatiSutta which is the preparing of MN MahasatipatthanaSutta.
Seeing that the hindrances have been given up in them, joy springs up. Being joyful, rapture springs up. When the mind is full of rapture, the body becomes tranquil. When the body is tranquil, they feel bliss. And when blissful, the mind becomes immersed.

They drench, steep, fill, and spread their body with rapture and bliss born of seclusion. There’s no part of the body that’s not spread with rapture and bliss born of seclusion.

Then, Prince, Brahmā Sahampati, having arranged his upper robe over one shoulder, having saluted me with joined palms, spoke thus to me: ‘Lord, let the Lord teach Dhamma, let the well-farer teach Dhamma; there are beings with little dust in their eyes who; not hearing Dhamma, are decaying, (but if) they are learners of Dhamma they will grow.’ Thus spoke Brahmā Sahampati to me, Prince; having said this, he further spoke thus:
