That’s the point, it is so you don’t have to require any special tools that you have to purchase or rent, or having to deal with glue and all that crap.

That’s not the point. The point is reduce electronic waste and improve lithium recovery. The regulations have the following provisions for replaceable batteries

A portable battery should be considered to be removable by the end-user when it can be removed with the use of commercially available tools and without requiring the use of specialised tools, unless they are provided free of charge, or proprietary tools, thermal energy or solvents to disassemble it.

Addition provision for waterproofing also may apply

To ensure the safety of end-users, this Regulation should provide for a limited derogation for portable batteries from the removability and replaceability requirements set for portable batteries concerning appliances that incorporate portable batteries and that are specifically designed to be used, for the majority of the active service of the appliance, in an environment that is regularly subject to splashing water, water streams or water immersion and that are intended to be washable or rinseable. … Where the derogation applies, the product should be designed in such a way as to make the battery removable and replaceable only by independent professionals, and not by end-users.

So basically most companies will opt either provide the tools for free like some already do or just claim that watches and headphones undergo enough contact with sweat and oils that apply for the derogation

I’ve heard good things about backblaze which has an s3 compatible API (meaning it supports most tools). Like s3 this probably means it has a similar learning curve
