Retraining Archetypes / Bloodlines etc. w / Bonus feats

[Taenia]

How does this work exactly?

For example, I am playing a Abyssal bloodline sorcerer and at 7th level I take augment summoning as a bonus feat. As a base feat I take Blindfight.

I decide i want to go into DD so I retrain my bloodline from Abyssal to Draconic. Do I lose the bonus feat? Do I replace my bonus feat? Can I choose to take Blindfight and then replace blindfight with Augment Summoning (assuming I had SF - Conjuration already)?

You lose any abilities granted by Abyssal, including bonus feats, class skills, arcana, and so on, and gain the abilities granted by Draconic.

Retrain your bloodline. Doing so replaces your bonus spells, bloodline arcana, bloodline feats, and bloodline powers. This training takes 5 days for every bonus feat, bloodline arcana, and bloodline power you lose from changing bloodlines. See also retraining feats and retraining spells known.

You essentially have to retrain everything at once, which could take a lot of downtime and coin. You can't keep anything from Abyssal unless Draconic also grants it.

What about bonus feats? What if you retrain out of an archetype that gives feats you can't have with the base class? Like a flowing monk going back to regular monk?
