1. Except now you need a new PCB, a new subassembly, new procedures...
2. You need a lot of fancy things, just not cell balancing. That “battery health indicator” all iphones have, guess where that’s from.
You can take it from someone who has built several devices with replaceable batteries, or we can just keep debating until I’ve fully explain to you how you actually build one of these.
The thing is, I don’t want to waste more time on this, you can do your research on your own, or just keep your preconceptions, whatever floats your boat.

Every phone needs new subassemblies and procedures. For the PCB, you end up with an extra one that's tiny true.

Sure, okay.

Where would I look?
I'm trying to follow your logic. But you mostly keep naming things phones already have. They already have all this engineering work. They already have the battery chip, it just changes location. And that chip is less than $3.
Could you please give me a couple sentence explanation of how you arrived at 20-30% for a phone that's designed from the start to have a removable battery? You keep nitpicking me for not understanding an argument that you never explained!
My understanding goes something like this: Posit a $600 phone of which $50 is the battery pouch. Remove battery pouch and chip from phone, replace with a connector, phone now costs $550? Add plastic shell and $3 chip and connector and tiny PCB onto the battery pouch. For the total price to rise 20%, doing that has to cost more than $100 and leave you with a battery that costs more than $150. How?
And phones didn't get massively cheaper when they stopped letting you remove batteries...
